Fetal neck masses are a complex and diverse group of anomalies that can present diagnostic and management challenges for clinicians. In addition to prenatal ultrasound, fetal magnetic resonance imaging (MRI) has emerged as a powerful tool for the evaluation of these masses due to its high soft tissue contrast and ability to provide detailed anatomical information, especially with respect to the fetal airway and mediastinum. This educational exhibit explores the use of fetal MRI in the assessment of 7 different head and neck masses encountered at our institution, including providing a diagnostic approach, describing imaging features, and demonstrating the utility of fetal MRI in predicting the level of airway management the fetus may need, providing important implications for prenatal counseling and delivery management.

Twin molar pregnancy featuring a complete hydatidiform mole and a coexisting live fetus is a rare but important condition with unique imaging findings. A 24-year-old pregnant female presented for concern for molar pregnancy on ultrasound at an outside facility. The gestational age of the pregnancy at presentation was 22 weeks and 6 days. MRI was obtained which revealed a single living fetus in cephalic presentation. Along the anterior and left lateral uterine body/fundus was a large lesion with multiple small discrete T2 hyperintense cysts intermixed with more solid T2 isointense components, as well as T2 hypointense, T1 hyperintense foci consistent with hemorrhagic products. The lesion was distinct and did not arise from the placenta. Same day ultrasound revealed a “snowstorm” appearance, consistent with twin molar pregnancy with a complete hydatidiform form and coexistent live fetus. Read More

Meroanencephaly is an extremely rare open neural tube under anencephaly spectrum with midline superior calvarial defect, herniation of disorganised brain parenchyma through the defect with deficient overlying skin. Anencephaly has an incidence of 0.1% on antenatal ultrasound, meroanencephaly is even rarer accounting for 3.4% cases of anencephaly. MRI is the modality of choice for complete assessment of meroanencephaly and antenatal ultrasonographic findings should be confirmed with fetal MRI.
A 35-year-old female presented for fetal MRI after suspicion of occipital encephalocele on antenatal ultrasound. MRI showed microcephaly with thin and abnormally shaped calvarium, a midline calvarial defect in the region of vertex with brain parenchyma protruding through the defect and deficient overlying skin covering. Meningeal covering was difficult to assess due to oligohydroamnios and close apposition of skull to uterine wall. There was absence of ventricular system and lack of normal supratentorial and infratentorial anatomical landmarks. Fetal face was normal. Persistent fetal thoracic kyphotic curvature was observed throughout the examination, spinal cord and spinal canal were normal with no spinal dysraphism. No other anomalies were demonstrated.

Infantile myofibromatosis (IM) is a rare congenital disease of early childhood. Approximately 50% of cases are diagnosed prenatally, and 90% are diagnosed prior to 2 years of age. Solitary IM, multicentric IM without visceral involvement, and generalized IM with cutaneous and visceral involvement have been described, with generalized IM carrying a poor prognosis and high mortality rate. The following reported case demonstrates an unusually high disease burden.
The patient was a monochorionic diamniotic twin fetus found to have a cystic and solid left facial mass on routine prenatal anatomy scan. Initial differential included congenital hemangioma, as well as lymphatic malformation and teratoma. Multiple prenatal ultrasounds and fetal MRI were obtained between gestational age 22w0d and delivery. At 32w2d, a new large paraspinal mass extending from the thoracic spine to the proximal right lower extremity was noted. During retrospective review, mild soft tissue thickening was noted in this region on fetal MRI. At this point, a vascular malformation was favored, with a differential of congenital rhabdomyosarcoma less likely. Ultrasound surveillance for the remainder of the pregnancy showed enlargement of the paraspinal mass with extension into the right retroperitoneal space.
The patient was delivered at 35w0d gestation via cesarean-section. On physical examination, she was found to have multiple masses involving the face, and the paraspinal, buttock, and bilateral lower extremity soft tissues. While atrophic papules were present, there were no overlying skin changes as would be expected with vascular malformations. Given the firmness of the masses and atrophic papules, the diagnosis of infantile myofibromatosis was suspected.
Whole-body MRI with contrast was obtained, demonstrating extensive heterogeneously enhancing soft tissue masses involving the left check, lower back extending into the retroperitoneal space, bilateral gluteal muscle and lower extremities.
The patient’s clinical status declined, and given the poor prognosis, was transitioned to comfort care and expired at age 2 months. Post-mortem autopsy confirmed the diagnosis of generalized infantile myofibromatosis with innumerable myofibromas of the right atrium, ventricles, intercostal muscle, diaphragm, thyroid, lungs, pancreas, adrenal glands, vertebrae, and paraspinal muscles.
The surviving twin is currently 2 years of age and is screened with whole-body MRI annually without evidence of disease. Read More

Previous studies show that phase contrast MRI (PC-MRI) can successfully measure fetal blood flow in late gestation singleton fetuses. To date there is a paucity of data quantifying fetal blood flow of twin or early gestational age pregnancies (~19 weeks). Twin-twin transfusion syndrome (TTTS) is a rare complication of monochorionic pregnancies that is believed to result from inequal flow distribution between fetuses. In this novel investigation, we utilized PC-MRI to investigate fetal aortic flow in early gestational age fetuses with TTTS or selective Intrauterine Growth Restriction (sIUGR). We compared flow distribution between the smaller and larger fetus in each twin pair. Read More

Diffusion-weighted Magnetic Resonance Imaging (dMRI) is increasingly used to study the fetal brain in utero. dMRI enables streamlined tractography, a computation with unique applications such as white matter tract-specific analysis and structural connectivity assessment. However, due to low fetal dMRI data quality and the challenging nature of tractography, existing methods often produce highly inaccurate results. This study addresses these challenges by proposing an anatomically constrained tractography method that accurately segments fetal brain tissue directly within dMRI. Read More

Congenital anomalies causing lower extremity shortening can result from dysgenesis or agenesis of the bones of the thigh, leg or foot; they are generally a very uncommon occurrence, with an incidence on the order of one case per 1,000,000 to one case per 100,000 births. These conditions result in varying degrees of morbidity, ranging from gait dysfunction to complete lack of the ability to ambulate. The accurate characterization of such an anomaly may be challenging prenatally, but can have significant impact on prognosis and treatment planning.
We present a collection of cases depicting the spectrum of prenatally diagnosed anomalies of limb development, including proximal focal femoral deficiency, multiple cases of varying degrees of fibular and tibial hemimelia, amniotic band syndrome, benign uterine packing, neurofibromatosis, clubfoot anomaly and rocker bottom foot, all of which were evaluated on prenatal ultrasound and/or fetal MRI.
Accurate prenatal diagnosis is extremely important for prognosis, treatment planning and risk-stratification for associated congenital anomalies. The purpose of this poster will be to highlight the imaging features by both fetal MRI and prenatal US, discuss potential diagnostic pitfalls and review the clinical implications of this interesting spectrum of congenital disorders. We will describe a methodical approach to assessment of these patients. Our recommendations include: prenatal US to include a complete set of bilateral long bone and foot length measurements; lateral and footprint views of the fetal foot; views of both tibiae and fibulae bilaterally; views of the spine and upper extremities, a thorough search for other abnormalities; fetal MRI for complex cases or when US findings are limited; and a complete family and maternal history, including notation of family stature.
Examples of the classic appearance of these conditions will be presented. Several missed diagnoses and the lessons learned will also be discussed. Counseling points addressed by the orthopedic surgeon will be included. Outcome management will be reviewed. Read More

Atretic cephalocele is a rare type of neural tube defect that occurs in the parietal or occipital scalp. Most cases present postnatally with a scalp nodule which may also have associated skin and hair abnormalities. We will present a case of atretic cephalocele diagnosed with fetal MRI as well as two additional cases of postnatally diagnosed atretic cephalocele in different patients.

A 26 week gestational age male fetus was found to have ventriculomegaly on routine OB ultrasound and was referred to maternal fetal medicine. Further ultrasound imaging demonstrated features suspicious for a posterior fossa encephalocele. A fetal MRI was then performed which demonstrated imaging findings consistent with an atretic cephalocele.

The imaging findings associated with atretic cephalocele including embryologic positioning of the straight sinus, the “spinning top” appearance of the tentorial incisura, and the “cigar shaped” CSF tract in the interhemispheric fissure will be illustrated in the exhibit using both fetal and postnatal MRI. Although the exact embryological development of atretic cephaloceles is not completely understood, the proposed mechanisms will be discussed. A brief summary of the associated syndromes and clinical outcomes reported in the literature will be presented.

Atretic cephalocele is a rare condition that is usually diagnosed postnatally with several characteristic imaging findings. These same abnormalities can also be seen on fetal MRI which can lead to an earlier diagnosis and more appropriate family counseling. 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. Read More

Fetal demise (FD) occurs in 1/1000 pregnancies after 20 weeks gestation. MRI is increasingly being used after ultrasound to assess fetal pathology. FD may occur in the interval between ultrasound and MRI, and various organ systems have been described as having changes on fetal MRI. Although ultrasound findings of FD have been well described, criteria for FD on MRI have not. Diffusion MRI evaluates Na⁺/K⁺ channel viability and can be used to evaluate tissue death. Flowing blood produces signal loss on MRI, and along with fetal heart activity results in MRI signal loss of the cardiac chambers. FD with no heart motion and increased signal within non-flowing blood in the heart should result in increased signal in the chambers relative to the myocardium. Either of these findings can be seen with different fetal pathology, but the combination of brain and cardiac changes may allow for a diagnosis of FD. We hypothesize that restricted brain diffusion in certain brain lobes along with increased signal within heart chambers is specific for FD. Read More

Fetal intracranial volume is one of the most important parameters used in assessing normal fetal growth. Based on volumetric ultrasound (US), Virtual Organ Computer-Aided-anaLysis (VOCAL^TM) is a commonly used technique for such measurement. Magnetic resonance imaging (MRI) offers better soft tissue contrast for fetal brain imaging and is considered as one of the best tools for tissue volumetry, and as a standard for comparison. In this work we compare fetal intracranial volumes measured from MRI with those obtained from VOCAL^TM measurements in the same fetuses. Read More

As an inexpensive modality that does not require ionizing radiation, ultrasound is the preferred method for screening for fetal anomalies. When an abnormality is detected on ultrasound, the limitations of the modality often elicit further evaluation with MRI, as MRI can provide more detail and information to the radiologist and clinician. Chest and cardiac pathologies are among the most common findings on prenatal ultrasound and often warrant additional imaging. Consequently, an understanding of these findings and how they appear on different modalities is essential to the pediatric imager.
This electronic exhibit features fetal ultrasound and MRI of mediastinal lymphangioma, type I-III congenital pulmonary airway malformations, intralobar, extralobar, and subdiaphragmatic sequestrations, left and right sided congenital diaphragmatic hernias, hypoplastic left heart, heterotaxy, AV canal defect, and rhabdomyoma. In addition to reviewing the correlation of findings on ultrasound and MRI, prognosis as well as conditions and syndromes commonly associated with these chest and cardiac anomalies will be examined.
The goal of this exhibit is to provide an overview of common fetal cardiopulmonary abnormalities on different, complementary imaging modalities. Familiarity with these conditions is necessary for the radiologist to provide critical information to clinicians to allow prompt intervention in the postnatal period. These findings can additionally serve as an indication to the radiologist to search for associated findings, allowing prognostication and appropriate counseling of parents. Read More

Dandy-Walker continuum is a group of posterior-fossa malformations which presents as posterior-fossa cyst with variable degree of vermian hypoplasia on antenatal ultrasound. However, evaluation of posterior fossa is limited on antenatal ultrasound. Fetal MRI provides excellent evaluation of posterior fossa including cerebellar vermis and biometric measurements for accurate characterization of Dandy-Walker Continuum which includes classic Dandy-Walker malformation, Vermian hypoplasia, Blake pouch cyst and Mega cisterna magna (in the order of severity).
In this pictorial review we will provide a step-wise approach for accurate characterization of Dandy-Walker continuum on fetal MRI through various case-based illustrations, biometric measurements (tegmentovermian angle, vermian and lateral ventricle size) and position of 4th ventricle choroid plexus. Associated findings like ventriculomegaly, corpus callosal agenesis, cortical migrational anomalies will also be demonstrated. This will aid pediatric radiologists in providing accurate antenatal diagnosis of Dandy-Walker continuum which is helpful for post-natal management as severe cases require immediate shunting and milder cases require only follow-up.

Case Presentation
A 27-year-old female patient, primigravida, with no pathological clinical history, and a low risk first-trimester screening for aneuploidy and preeclampsia. Morphological ultrasound was performed at 21 weeks of gestational age, revealing a cystic structure at the lumbosacral spine with bone alteration. Myelomeningocele was suspected, but no associated Chiari type II anomaly was observed. Additional Fetal Magnetic Resonance Imaging (Fetal MRI) was requested.

Findings
At 24 weeks, an obstetric ultrasound was made identifying a cystic image at the lumbosacral level with the absence of a placode. An osseous spur protruding into the medullary canal was observed, dividing the medullary cone in two. Suspicious fatty tissue suggestive of a lipoma was also noted. Fetal MRI confirmed the ultrasound findings, consistent with diastematomyelia (DM) associated with closed meningocele, lipoma, and medullary canal ectasia.

Discussion
Dysraphism are congenital malformations of the spinal canal, with a prevalence of 1 to 3 per 1000 live births, and the lumbosacral spine being the most commonly affected site.
DM is a closed-type dysraphia in which there is a splitting of the spinal cord into two halves separated by a fibrous, cartilaginous, or bony septum. Clinical manifestations are variable and are typically related to orthopedic problems, urinary or fecal incontinence, and characteristic cutaneous abnormalities.
When isolated, DM tends to have a favorable prognosis, but approximately one-third of affected patients have an accompanying dysraphism. Current recommendations include early postnatal surgery to prevent further complications.

Conclusion
DM is a rare disorder of spinal development that can be diagnosed prenatally through imaging. Precise identification of the lesion and the exclusion of other associated structural malformations are crucial for prognosis. Read More

Stillbirth is a sad complication of pregnancy. Establishing the cause of death in intrauterine fetal demise (IUFD) is important to bring psychological closure to the family and crucial for reproductive counseling. The gold standard to establish the cause of IUFD is perinatal autopsy. However, perinatal autopsy rates are falling worldwide, largely attributed to patients and physicians discomfort with death and discussion of postmortem examinations as well as social and religious reasons. There is a lack of experience with minimally invasive perinatal autopsy in the United States and even more limited publications in the subject. Our main goal was to investigate the added value of postmortem MRI to conventional autopsy in the clinical setting. Our program has had successes and failures, of which learning opportunities exist for other institutions that desire to implement similar programs. This paper will discuss the timeline of our progress and share examples of potential roadblocks and keys to success in implementing such a program. Read More

Urinary tract dilation (UTD) is a common finding in fetal and neonatal imaging, and accurate classification is essential for guiding management and determining prognosis. This educational exhibit provides a comprehensive review of the UTD classification system, with a focus on the findings on fetal ultrasound (US), fetal MRI and postnatal imaging. In addition to the classification system, we will explore the etiologies of UTD, including obstructive and non-obstructive causes such as vesicoureteral reflux, ureteropelvic junction obstruction, and posterior urethral valves. Special emphasis will be placed on the role of prenatal and postnatal imaging in monitoring progression and guiding management decisions, including when surgical intervention may be necessary. We aim to enhance the understanding of the diagnostic criteria for UTD, provide insight into the correlation between imaging findings and clinical outcomes, and equip pediatric radiologists with the tools to make informed management recommendations. This review will aid in the accurate diagnosis and treatment of UTD, ultimately improving outcomes for affected neonates. Read More
