Most congenital lung anomalies are discovered in utero, often at the early 2nd trimester US screening, this may be followed by a prenatal MR for more detailed characterization. Many “mass-like” lesions decrease in size and conspicuity during the 3rd trimester and are asymptomatic and not visible or missed with only subtle changes on a postnatal chest radiograph. A 3–6-month postnatal CT or MR scan is often obtained to visualize the lesion and evaluate its features, size and extent and decide on surgical or conservative management. Lesions that are not diagnosed prenatally, dismissed or forgotten because of a normal appearing neonatal CXR or are managed conservatively or with partial surgical treatment (e.g. multiple lesions or incomplete resection) may be seen later in life either incidentally, in follow-up or with associated complications such as infection. Additionally, there are several acquired entities that can mimic or be mistaken for congenital lung anomalies. This poster will review and illustrate the late presentation of multiple congenital lung lesions beyond the neonatal period including bronchogenic cyst, lobar/segmental bronchial atresia and overinflation, CPAM, sequestration and hybrid CPAM/sequestration, several with clinical symptoms/complications as well as residual post-surgical lesions. Mimics of congenital lung lesions illustrated will include infectious acquired lobar overinflation, mediastinal lesion compressing airway causing lung/lobar overinflation and pneumonia with pneumatoceles mimicking infected CPAM.

Causes of paucity of bowel gas in the neonate abdomen can vary widely. This case series will review common and uncommon causes of paucity of bowel gas on abdominal radiography in the newborn as well as further imaging strategies to achieve a rapid diagnosis. Entities range from solid organ enlargement and masses as well as diseases of bowel origin. Evaluation of the most common causes of the lack of bowel gas with x-ray, ultrasound and fluoroscopy can lead to rapid diagnosis and treatment, especially if not prenatally diagnosed. This series will also discuss the utility of post-natal CT and/or MRI in select cases. Read More

To identify patterns of calcifications and location on abdominal radiography to help diagnose their disease processes. We retrospectively reviewed abdominal x-rays with abnormal calcifications and correlated the findings with additional imaging such as ultrasound, CT or MR. We grouped calcifications by quadrant or diffuse to correlate with the differential diagnosis and disease process. Assessing the location and characteristics of calcifications on abdominal radiography can be highly useful in aiding in the formation of a differential diagnosis and guide next imaging steps.

The development and migration of reproductive organs is a complex process that is often poorly understood. Abnormally located testes and ovaries may reflect an incidental transient finding or underlying/pending pathology. Cryptorchidism is the most common genitourinary anomaly in males with associated increased risk of infertility and malignancy. Ectopic testes (outside the normal line of descent) have been reported within the perineum, penis, and femoral canal, representing a rare- but important entity to recognize and diagnose. Abnormally positioned ovaries- either in the midline pelvis or within the canal of Nuck- may mimic tumors or reflect underlying vascular compromise of the tissue. This educational exhibit will present a case-based review of the normal migration and anatomic position of gonadal tissue, as well as common and uncommon aberrant locations. In addition, this exhibit will highlight imaging strategies, including appropriate modalities and techniques. A brief discussion of current concepts in management will also be provided. Read More

The pediatric thymus is a constant but confusing, dynamic entity. The goal of this educational exhibit is to illustrate the range of appearances of the normal thymus and to identify key imaging features that can help pediatric radiologists differentiate normal thymic tissue from neoplastic conditions and other mimics.
