The purpose of this exhibit is to make radiologists and clinicians aware of the different disease entities, which involve avascular necrosis. Additionally, we will discuss the different locations in which avascular necrosis can occur and the different pathogenic mechanisms which contribute. Avascular necrosis has a wide variety of etiologies and can affect nearly every bone in the human body. Many sites of involvement are given eponyms associated with the corresponding area. These sites are to be discussed individually, as many have unique clinical and prognostic features. We aim to educate radiologists and clinicians regarding the imaging characteristics of avascular necrosis in the various diseases discussed. Read More

The pediatric population is not immune to the various types of cancer encountered by the adult population in terms of the organs and organ systems affected. Despite advances in treatments and detection, cancer is still the number 2 cause of death within the pediatric population. The types of tumors encountered in the younger population are often composed of more uniquely immature cellular lineages and only a small percentage have preventable causes. The goal of our single institution presentation is to provide the interested viewer with a comprehensive review of several uniquely encountered immature pediatric tumors. Our presentation will include imaging examples utilizing multiple modalities demonstrating examples of pancreaticoblastoma , immature lipoblastoma, neuroblastoma, hepatoblastoma, a case of biopsy confirmed small cell undifferentiated renal rhabdoid tumor, and a unique case of pleuropulmonary blastoma. Explanations pertaining to the key imaging features of each entity as reported in the literature will be provided to supplement the case examples from our institution. Read More

MRI evaluation of the placenta, and particularly placental vascularity, is a critical yet challenging task for the radiologist. Failure to accurately diagnose ischemic changes or to detect signs of the abnormally invasive placenta can have devastating consequences for both maternal and fetal patients. The radiologist's task is further complicated by the inability to use intravenous contrast.

In this presentation, we outline a 7-point, systematic method for evaluation of the placenta, highlighting key changes in appearance and signal intensity between 1.5T and 3T MR field strength, and also incorporating a novel method for evaluating blood flow within placental parenchyma utilizing a hybrid image derived from (noncontrast) SSFP and SSFSE pulse sequences. Our systematic approach analyzes the following diagnostic criteria: location, presence of deep vessels, presence of enlarged/ectatic vessels, presence of fibrin/blood products, disruption of uterine myometrial signal, focal bulge, and signal irregularity of the bladder dome. Finally, we correlate this diagnostic method with a quantitative scoring system which can further aid with delivery planning and prognostication.

In preterm infants, caudothalamic lesions on ultrasound usually evoke the presence of a recent germinal matrix bleed. Intraventricular bleeds may also be seen in term infants but usually located near the glomus of the choroid plexus. Because germinal matrix has involuted in term infants, caudothalamic bleeds are infrequent and other possibilities should be considered when caudothalamic lesions are seen. Previous literature has described germinolytic cysts as indistinguishable from lesions resulting from germinal matrix hemorrhage. The pathologic process underlying development of these cysts is not well known and may result from intrauterine injury due to a vascular insult, congenital infections or chromosomal abnormalities. In our practice, we have seen many cases of germinolytic cysts in term infants mimicking germinal matrix bleed but acting as “red flag” raising the suspicion of other pathology, such as CMV infection and Zellweger syndrome. Although germinal matrix bleed and germinolytic cysts appear similar on ultrasound, we believe that key differentiating feature between these lesions is gestational age of the infant at presentation.
Purpose of our educational exhibit is to emphasize these facts and encourage both radiologists and sonologists to consider unusual but important possibilities such as CMV infections or Zellweger syndrome whenever caudothalamic lesions are encountered in a term baby. We discuss other abnormalities and findings to support these diagnoses. Early suspicion and detection of intracranial CMV infection is essential for prompt treatment and better outcome.

Stress injuries occur when normal bone is subjected to chronic and repeated mechanical loading. Children are at particularly increased risk for these types of injuries compared to adults, due to weaker chondro-osseous junctions, increased physical activity, less muscle mass, narrower bones with thinner cortices, hormonal changes, and decreased mineral content of bones.

Pediatric stress injuries consist of physeal and apophyseal stress injuries and stress fractures. When the primary physes of the long bones sustain repetitive workloads, endochondral ossification is impeded, and unmineralized cartilage extends into the metaphysis. Such repetitive workloads also affect associated apophyses, leading to chondrocyte proliferation, hypertrophy, and inflammation. Stress fractures, also known as fatigue fractures, occur when bone remodeling is given insufficient time to repair “micro-trauma” damage and additional mechanical loading cycles enable damage to accumulate in the bone, ultimately leading to a fracture.

This educational exhibit will review the imaging findings associated with stress injuries of the axial and appendicular skeleton commonly seen in older children and adolescents. The exhibit will draw on case examples of children participating in a wide range of activities to illustrate the range of stress injuries in the pediatric population and their diagnostic findings, including cheerleading, dancing, baseball pitching, climbing, and even bowling and competitive yoga.

Five years ago the leaders of the world’s regional pediatric imaging societies launched the World Federation of Pediatric Imaging (WFPI), a pediatric imaging body with global overview. According to its mission statement "WFPI provides an international platform for pediatric radiology organizations united to address the challenges in global pediatric imaging training and the delivery of services".
To guide WFPI's outreach endeavors as well as of other organizations interested in improving pediatric radiology services worldwide a project to better define the needs and gaps of pediatric radiologists and training centers worldwide was undertaken.
The project aims to:
-Establish the number of Pediatric Radiologists (as regionally defined) per country/region around the world
-Outline the training pediatric radiologists receive and availability of training centers
-Highlight major disparities and gaps in availability of pediatric radiologists and pediatric imaging training
-Based on this information create a roadmap for WFPI’s global efforts.

Functional magnetic resonance urography (fMRU) provides not only anatomic information but quantitative functional information as well. Several free tools are available to perform functional analysis. One such tool, CHOP-fMRU, is appealing because its creators have provided extensive instructions on their software and scan protocols.

Several barriers were encountered in attempting to implement CHOP-fMRU at OHSU. First, to perform the analysis, the appropriate DICOM files must be acquired from PACS. CHOP-fMRU is compatible with a limited number of transfer syntaxes, so a conversion is required after PACS download if the encoding is incompatible. Second, CHOP-fMRU is incompatible with some types of data elements that can be found in files with valid DICOM formats. Third, only the dynamic series can be included when importing a study into CHOP-fMRU, and every image in the set must be present. If an image from another series is included or an image from the dynamic series is excluded, the user encounters an error. Finally, when the analysis has been performed, it is desirable to send the results to PACS. Unless the user has purchased an Interactive Data Language (IDL) license, the images may only be exported as JPEG files. These files must be packaged into DICOM files with the correct header data before they are sent to PACS using DICOM network protocol.

While these tasks could each be accomplished with any one of many available DICOM tools, some of the tasks are moderately complex, and performing them manually would be time consuming. Instead, an additional piece of software desigend solely to perform these functions as simply and efficiently as possible can be helpful. Such a solution was attempted at OHSU, and the resulting software, CHOP-fMRU Assistant, is presented here.

CHOP-fMRU Assistant is a program written in C# using the Grassroots DICOM (GDCM) library. Current features include automatic transfer syntax conversion, removal of many potentially incompatible data elements, easy exclusion of unwanted series, analysis of the dynamic series for missing images, and conversion of the results from CHOP-fMRU to DICOM files for upload to PACS. CHOP-fMRU Assistant is available at https://github.com/overtone1000/CHOP-fMRU_Assistant under an open-source license and is offered with an associated wiki to help other institutions who have encountered similar barriers while attempting to implement CHOP-fMRU.

Congenital high airways obstruction sequence (CHAOS) refers to a relatively rare fetal anomaly caused by high airway obstruction (tracheal or laryngeal) caused by atresia or stenosis. Similar imaging findings can be seen with airway obstruction due to oropharyngeal or neck masses such as teratoma. Antenatal imagining findings include but not limited to dilated fluid filled trachea and proximal bronchi, bilateral enlarged echogenic lungs with relative small sized midline heart, flattening or eversion of the diaphragm, feta ascites and anasarca and polyhydramnios. The prognosis is overall poor, however it is improved after planning for delivery and performing EXIT procedure (ex utero intrapartum treatment) with tracheostomy.
We present a case of a 20-year-old female G1P0 at 25 weeks of gestation diagnosed with Congenital high airways obstruction sequence (CHAOS) with typical features on prenatal ultrasound and fetal MR. Delivery was planned and an EXIT procedure was performed and the newborn survived.

Congenital diaphragmatic hernia (CDH) is the result of incomplete closure of the normal pleuroperitoneal canal. CDH is usually detected prenatally or present in the newborn period with severe respiratory distress. In contrast, delayed presentation of CDH (D-CDH), defined as CDH diagnosed at later than 30 days of age, is known as rare subset of CDH. The outcome of patients with D-CDH is generally favorable, but misdiagnosis can result in morbidity and mortality. This educational exhibit will demonstrate clinico-radiological characteristics of D-CDH. Read More

Colonic volvulus is an uncommon but often catastrophic condition in children. Imaging studies including plain radiographs, ultrasound, fluoroscopy, and computed tomography are commonly employed to evaluate these patients. While most radiologists are familiar with malrotation and midgut volvulus, colonic volvulus is an underappreciated cause of an acute abdomen in children. Symptoms of colonic volvulus may be vague, and presentation is often delayed. While plain radiographs may be highly suggestive in some patients, they are often nonspecific. Fluoroscopy and CT are usually diagnostic and can direct appropriate operative management. The purpose of this exhibit is to present the imaging appearances of cecal and sigmoid volvulus in children, emphasizing the plain radiographic features suggestive of these entities and the diagnostic fluoroscopic and CT features that allow definitive diagnosis.

The purpose of this case series is to describe the variable prenatal presentation of lethal and nonlethal hypophosphatasia, obstetrical outcomes, and postnatal course of the nonlethal cases.

5 genetically proven cases of hypophosphatasia were evaluated in our fetal imaging center from 2009 to 2016 and initially imaged between 17 weeks and 34 weeks gestation. The prenatal imaging, prenatal testing, pregnancy outcome, and postnatal or autopsy imaging and genetic testing are reviewed in this case series.

All 5 cases were referred with a high suspicion of a skeletal dysplasia. Fetal sonography demonstrated a spectrum of bowing, shortening, and acute fractures of the long bones, variable involvement of the upper and lower extremities, and axial skeleton involvement.
Of the 5 cases, 3 were nonlethal. Postnatal imaging in these cases was concordant with the prenatal assessment of variable mild limb shortening and bowing and without involvement of the axial skeleton.
Case 4 was terminated at 20 weeks due to severe micromelia and irregular long bones with postmortem radiographs demonstrating shortening and fractures with severe demineralization of the skull.
Case 5, first evaluated at 29 weeks gestation demonstrated severe bowing and shortening of the long bones, a small chest circumference with beading of the ribs. Postnatal radiographs demonstrated spurs in the midshafts of the fibula and ulna with severely demineralized skull. The infant died in the immediate postnatal period.

MRI evaluation of the placenta, and particularly placental vascularity, is a critical yet challenging task for the radiologist. Failure to accurately diagnose ischemic changes or to detect signs of the abnormally invasive placenta can have devastating consequences for both maternal and fetal patients. The radiologist's task is further complicated by the inability to use intravenous contrast.

In this presentation, we outline a 7-point, systematic method for evaluation of the placenta, highlighting key changes in appearance and signal intensity between 1.5T and 3T MR field strength, and also incorporating a novel method for evaluating blood flow within placental parenchyma utilizing a hybrid image derived from (noncontrast) SSFP and SSFSE pulse sequences. Our systematic approach analyzes the following diagnostic criteria: location, presence of deep vessels, presence of enlarged/ectatic vessels, presence of fibrin/blood products, disruption of uterine myometrial signal, focal bulge, and signal irregularity of the bladder dome. Finally, we correlate this diagnostic method with a quantitative scoring system which can further aid with delivery planning and prognostication.

Stress injuries occur when normal bone is subjected to chronic and repeated mechanical loading. Children are at particularly increased risk for these types of injuries compared to adults, due to weaker chondro-osseous junctions, increased physical activity, less muscle mass, narrower bones with thinner cortices, hormonal changes, and decreased mineral content of bones.

Pediatric stress injuries consist of physeal and apophyseal stress injuries and stress fractures. When the primary physes of the long bones sustain repetitive workloads, endochondral ossification is impeded, and unmineralized cartilage extends into the metaphysis. Such repetitive workloads also affect associated apophyses, leading to chondrocyte proliferation, hypertrophy, and inflammation. Stress fractures, also known as fatigue fractures, occur when bone remodeling is given insufficient time to repair “micro-trauma” damage and additional mechanical loading cycles enable damage to accumulate in the bone, ultimately leading to a fracture.

This educational exhibit will review the imaging findings associated with stress injuries of the axial and appendicular skeleton commonly seen in older children and adolescents. The exhibit will draw on case examples of children participating in a wide range of activities to illustrate the range of stress injuries in the pediatric population and their diagnostic findings, including cheerleading, dancing, baseball pitching, climbing, and even bowling and competitive yoga.

Congenital high airways obstruction sequence (CHAOS) refers to a relatively rare fetal anomaly caused by high airway obstruction (tracheal or laryngeal) caused by atresia or stenosis. Similar imaging findings can be seen with airway obstruction due to oropharyngeal or neck masses such as teratoma. Antenatal imagining findings include but not limited to dilated fluid filled trachea and proximal bronchi, bilateral enlarged echogenic lungs with relative small sized midline heart, flattening or eversion of the diaphragm, feta ascites and anasarca and polyhydramnios. The prognosis is overall poor, however it is improved after planning for delivery and performing EXIT procedure (ex utero intrapartum treatment) with tracheostomy.
We present a case of a 20-year-old female G1P0 at 25 weeks of gestation diagnosed with Congenital high airways obstruction sequence (CHAOS) with typical features on prenatal ultrasound and fetal MR. Delivery was planned and an EXIT procedure was performed and the newborn survived.

The purpose of this exhibit is to make radiologists and clinicians aware of the different disease entities, which involve avascular necrosis. Additionally, we will discuss the different locations in which avascular necrosis can occur and the different pathogenic mechanisms which contribute. Avascular necrosis has a wide variety of etiologies and can affect nearly every bone in the human body. Many sites of involvement are given eponyms associated with the corresponding area. These sites are to be discussed individually, as many have unique clinical and prognostic features. We aim to educate radiologists and clinicians regarding the imaging characteristics of avascular necrosis in the various diseases discussed. Read More

The purpose of this case series is to describe the variable prenatal presentation of lethal and nonlethal hypophosphatasia, obstetrical outcomes, and postnatal course of the nonlethal cases.

5 genetically proven cases of hypophosphatasia were evaluated in our fetal imaging center from 2009 to 2016 and initially imaged between 17 weeks and 34 weeks gestation. The prenatal imaging, prenatal testing, pregnancy outcome, and postnatal or autopsy imaging and genetic testing are reviewed in this case series.

All 5 cases were referred with a high suspicion of a skeletal dysplasia. Fetal sonography demonstrated a spectrum of bowing, shortening, and acute fractures of the long bones, variable involvement of the upper and lower extremities, and axial skeleton involvement.
Of the 5 cases, 3 were nonlethal. Postnatal imaging in these cases was concordant with the prenatal assessment of variable mild limb shortening and bowing and without involvement of the axial skeleton.
Case 4 was terminated at 20 weeks due to severe micromelia and irregular long bones with postmortem radiographs demonstrating shortening and fractures with severe demineralization of the skull.
Case 5, first evaluated at 29 weeks gestation demonstrated severe bowing and shortening of the long bones, a small chest circumference with beading of the ribs. Postnatal radiographs demonstrated spurs in the midshafts of the fibula and ulna with severely demineralized skull. The infant died in the immediate postnatal period.

In preterm infants, caudothalamic lesions on ultrasound usually evoke the presence of a recent germinal matrix bleed. Intraventricular bleeds may also be seen in term infants but usually located near the glomus of the choroid plexus. Because germinal matrix has involuted in term infants, caudothalamic bleeds are infrequent and other possibilities should be considered when caudothalamic lesions are seen. Previous literature has described germinolytic cysts as indistinguishable from lesions resulting from germinal matrix hemorrhage. The pathologic process underlying development of these cysts is not well known and may result from intrauterine injury due to a vascular insult, congenital infections or chromosomal abnormalities. In our practice, we have seen many cases of germinolytic cysts in term infants mimicking germinal matrix bleed but acting as “red flag” raising the suspicion of other pathology, such as CMV infection and Zellweger syndrome. Although germinal matrix bleed and germinolytic cysts appear similar on ultrasound, we believe that key differentiating feature between these lesions is gestational age of the infant at presentation.
Purpose of our educational exhibit is to emphasize these facts and encourage both radiologists and sonologists to consider unusual but important possibilities such as CMV infections or Zellweger syndrome whenever caudothalamic lesions are encountered in a term baby. We discuss other abnormalities and findings to support these diagnoses. Early suspicion and detection of intracranial CMV infection is essential for prompt treatment and better outcome.

Functional magnetic resonance urography (fMRU) provides not only anatomic information but quantitative functional information as well. Several free tools are available to perform functional analysis. One such tool, CHOP-fMRU, is appealing because its creators have provided extensive instructions on their software and scan protocols.

Several barriers were encountered in attempting to implement CHOP-fMRU at OHSU. First, to perform the analysis, the appropriate DICOM files must be acquired from PACS. CHOP-fMRU is compatible with a limited number of transfer syntaxes, so a conversion is required after PACS download if the encoding is incompatible. Second, CHOP-fMRU is incompatible with some types of data elements that can be found in files with valid DICOM formats. Third, only the dynamic series can be included when importing a study into CHOP-fMRU, and every image in the set must be present. If an image from another series is included or an image from the dynamic series is excluded, the user encounters an error. Finally, when the analysis has been performed, it is desirable to send the results to PACS. Unless the user has purchased an Interactive Data Language (IDL) license, the images may only be exported as JPEG files. These files must be packaged into DICOM files with the correct header data before they are sent to PACS using DICOM network protocol.

While these tasks could each be accomplished with any one of many available DICOM tools, some of the tasks are moderately complex, and performing them manually would be time consuming. Instead, an additional piece of software desigend solely to perform these functions as simply and efficiently as possible can be helpful. Such a solution was attempted at OHSU, and the resulting software, CHOP-fMRU Assistant, is presented here.

CHOP-fMRU Assistant is a program written in C# using the Grassroots DICOM (GDCM) library. Current features include automatic transfer syntax conversion, removal of many potentially incompatible data elements, easy exclusion of unwanted series, analysis of the dynamic series for missing images, and conversion of the results from CHOP-fMRU to DICOM files for upload to PACS. CHOP-fMRU Assistant is available at https://github.com/overtone1000/CHOP-fMRU_Assistant under an open-source license and is offered with an associated wiki to help other institutions who have encountered similar barriers while attempting to implement CHOP-fMRU.

Congenital diaphragmatic hernia (CDH) is the result of incomplete closure of the normal pleuroperitoneal canal. CDH is usually detected prenatally or present in the newborn period with severe respiratory distress. In contrast, delayed presentation of CDH (D-CDH), defined as CDH diagnosed at later than 30 days of age, is known as rare subset of CDH. The outcome of patients with D-CDH is generally favorable, but misdiagnosis can result in morbidity and mortality. This educational exhibit will demonstrate clinico-radiological characteristics of D-CDH. Read More

Colonic volvulus is an uncommon but often catastrophic condition in children. Imaging studies including plain radiographs, ultrasound, fluoroscopy, and computed tomography are commonly employed to evaluate these patients. While most radiologists are familiar with malrotation and midgut volvulus, colonic volvulus is an underappreciated cause of an acute abdomen in children. Symptoms of colonic volvulus may be vague, and presentation is often delayed. While plain radiographs may be highly suggestive in some patients, they are often nonspecific. Fluoroscopy and CT are usually diagnostic and can direct appropriate operative management. The purpose of this exhibit is to present the imaging appearances of cecal and sigmoid volvulus in children, emphasizing the plain radiographic features suggestive of these entities and the diagnostic fluoroscopic and CT features that allow definitive diagnosis.
