There are numerous congenital anomalies of the gastrointestinal tract with varying frequency. Some anomalies are life-threatening and require prompt diagnosis with immediate treatment. Evaluation of patients with these anomalies can be complex, sometimes requiring multiple imaging modalities for accurate diagnoses and timely treatment. It is therefore essential for radiologists to have a firm understanding of specific imaging features. The purpose of this exhibit is to review common and uncommon congenital anomalies of the gastrointestinal tract, including clinical and imaging features as well as treatment options. Read More

The female anatomic equivalent of the male processus vaginalis is the canal of Nuck. The canal is formed from a small peritoneal protuberance from the round ligament that extends through the inguinal ring, into the inguinal canal, and terminates in the labia majora. Obliteration of the canal occurs in a superior to inferior direction and usually completes within the first year of life. Non-closure results in a persistent canal of Nuck. Very rarely herniation of abdominal and pelvic contents into the canal of Nuck can occur, much less commonly in females than in the male equivalent. Hernias can present at any age but are most common in children. Recognition of this entity is especially important in cases of ovarian herniation due to the risk of incarceration. We will provide a review normal anatomy, potential canal contents, the imaging appearance on ultrasound, CT, as well as MRI, and discuss differential diagnosis using cases of canal of Nuck hernia in 4 patients aged 22 days though 17 years.

Ultrasound is a common screening examination performed in infants prior to closure of osseous posterior elements. Although radiologists with pediatric neuroradiology subspecialty training may be very familiar with many abnormalities encountered sonographically, pediatric radiologists without pediatric neuroradiology subspecialty training are often less familiar. Further, the ultrasound appearance of abnormalities of infant spine may be less well known than appearance on MRI. The purpose of this educational review is to demonstrate normal appearance of infant spine and illustrate abnormalities that are frequently and infrequently encountered during screening ultrasound evaluation, with MRI for comparison.

Timely intracranial imaging enables diagnosis, directs treatment, and provides prognostic information of infant malformation or injury. MRI is the gold standard for neuroimaging, but can be inhibited by transportation risk and incompatible support devices. Ultrasound (US) is portable, rapid, and inexpensive, but limited by lower sensitivity and specificity. Contrast-enhanced ultrasound (CEUS) improves diagnostic accuracy of US in other clinical applications. Our aim was to prospectively compare CEUS of the neonatal brain to MRI. Read More

Transfontanelle cranial ultrasound is widely used in the neonatal setting to screen for abnormalities, particularly in the neonatal and cardiac intensive care unit settings. Radiologists and sonographers are typically very familiar with the ultrasound appearance of germinal matrix hemorrhage in premature infants. However, other abnormalities can also be very well seen sonographically, but may be underappreciated and therefore underreported. Under recognition may delay appropriate therapy these infants. The purpose of this educational review is to demonstrate the sonographic findings in a variety of neonatal intracranial abnormities including ischemia, hemorrhage, as well as developmental and anatomical anomalies, and to compare them with what may be the more familiar cross sectional appearance, including CT and MRI.
