Ovarian torsion in pediatrics is challenging to diagnose, both clinically and radiologically. Ultrasound is most commonly used to evaluate for this process, though there are no sonographic findings that are pathognomonic. One sonographic finding that has been infrequently reported in the literature is medialization of the ovary (defined as the ovary at or crossing the midline of the uterus), as the adnexal structures are drawn inwards by the twisted broad ligament. Knowledge of this finding in addition to the other more classic findings of torsion can be an important clue to the diagnosis. This study evaluates the presence of ovarian medialization in a large number of cases of known torsion. Read More

Purpose Ovarian torsion is rare in neonates and infants. Clinical diagnosis is challenging in the setting of lack of specific symptoms and the limitations in assessing pain in infants. Torsed ovaries in this patient population are also a diagnostic dilemma on imaging. In this study we reviewed the spectrum of imaging findings with pathologic correlation in a large series of patients. Read More

Congenital vascular anomalies of the liver are rare entities that take on different physical forms and clinical presentations, with imaging being highly important in the diagnosis and follow-up of these entities. The purpose of this educational presentation is to provide a multimodality imaging review of several different congenital vascular anomalies of the liver that have been observed at a single pediatric tertiary care center. These include infantile hepatic hemangiomas, congenital portosystemic shunts, and congenital intrahepatic arterioportal shunt. The clinical course and management/treatment for each of these entities, to also include the role of imaging in follow-up, will also be briefly discussed. Read More

Fallopian tube torsion is a rare cause of acute abdominal pain in pediatric patients. Pelvic ultrasound is the first imaging modality utilized to evaluate for pelvic pathology, typically to rule out ovarian torsion. Ultrasound findings of fallopian tube torsion can be challenging, leading to delayed surgical intervention, particularly when ovaries have a normal gray scale appearance and spectral Doppler waveforms. We reviewed the ultrasound features of fallopian tube torsion in a series of surgically proven cases. Read More

Ventricular shunt failures are common with as many as 40% failing by 1 year and 70% by 10 years. Approximately 15% of these shunt failures are related to shunt disconnections. The typical presenting symptoms of shunt malfunction are nonspecific and include nausea, vomiting, and altered consciousness; therefore, imaging is critical for diagnosis. Conventional radiographs can be used to identify shunt disruption although they can have limited sensitivity. Most children with suspected shunt dysfunction will also undergo CT or MR imaging to evaluate ventricular sizes. In addition, the integrity of the shunt system within the field of view on head CT can be assessed in detail; however, subtle shunt disconnections or fractures can still be difficult to detect on multiplanar CT images. Volume rendered CT images of the shunt apparatus can be used to improve the detection of subtle shunt disruptions Read More

Pelvic ultrasound is commonly used to detect ovarian torsion, but the diagnosis remains challenging as there is no single pathognomonic feature. This retrospective case-controlled study aims to identify an algorithm to detect torsion based on common ultrasound imaging features. Read More

The general pediatric radiologist is well aware of the classic scintigraphic findings of common malignancies. However, atypical presentations, appearances, and complications related to treatment and resultant immunosuppression may confound diagnosis. We present a series of interesting cases to help our non-nuclear medicine trained colleagues develop a systematic approach to nuclear medicine image interpretation in atypical cases. Read More

Ultrasound has long been a readily available, noninvasive, and accurate means of evaluating the female pelvis and is widely used in the emergency setting for girls with abdominal and pelvic pain. One key element in evaluating for pathology is to measure ovarian size and compare left and right ovaries. Normative volume data stratified by age are available; however, these studies suffer from lack of numbers, and frequently older equipment. Technological advances in ultrasonic hardware and software have increased the resolution of both gray-scale and Doppler imaging. Increases in spatial resolution allow for better identification and measurement of ovaries and precise measurements and depictions of anatomic details. The purpose of this study was to re-evaluate normal pediatric ovarian volumes in relation to patient age with a larger dataset and newer technology. Read More

Ewing sarcoma is the second most common malignancy of bone with an incidence of approximately 200 cases per year in the United States in children under 20. Extraosseous Ewing sarcoma originating in the vagina is rare, with only 8 cases reported to date in the literature. These highly aggressive tumors require a more intensive treatment regimen compared to other vaginal masses like rhabdomyosarcoma. While the imaging findings are non-specific, awareness of this clinical entity can facilitate early diagnosis and appropriate treatment, which may improve prognosis. Read More
