Short Bowel Syndrome (SBS) is a significant cause of morbidity and mortality in neonates, resulting from a substantial reduction in functional small intestine. It may arise from congenital anomalies or acquired conditions requiring extensive bowel resection. This educational exhibit presents a review of the different pathologies potentially leading to SBS in neonates, to help radiologists offer an early and accurate diagnosis, critical to optimize clinical outcomes. We review and illustrate conditions using multimodality imaging in: 1. Congenital causes of SBD: Gastroschisis. Bowel atresia. Complicated meconium ileus. Meconium peritonitis and meconium pseudocyst. 2. Acquired causes of SBS: Malrotation and midgut volvulus. Necrotizing enterocolitis. Hirschsprung’s disease. This study aims to underscore the essential role of perinatal imaging in the early detection, characterization, and management planning of both congenital and acquired etiologies leading to SBS in the neonatal population. Emphasis is placed on the diagnostic utility of prenatal ultrasound and MRI and postnatal imaging techniques starting with plain radiography, contrast studies, and cross-sectional imaging in the neonatal period.

The fetal ganglionic eminence (GE) is a transient structure in the developing human brain, playing a crucial role in the formation of the cerebral cortex and other critical brain regions. The GE is primarily responsible for the production of GABAergic interneurons, which are essential for the proper functioning of the cerebral cortex. Understanding its anatomy and pathology is essential for identifying potential developmental disorders that may arise during prenatal life. Fetal MRI has emerged as a powerful tool in the assessment of brain development, offering high-resolution images that can reveal subtle changes in the anatomy of the GE. Through the use of fetal MRI radiologists can identify various alterations in the GE, such as cystic cavitations, enlargement, and other morphological changes that may indicate serious malformations in brain development, such as hemimegalencephaly or other cortical malformations. One of the significant advantages of fetal MRI is its ability to provide a comprehensive view of the fetal brain, enabling the identification of not only the GE but also its relationship with surrounding structures such as the lateral ventricles or the thalamus, which can further complicate the clinical picture. By utilizing fetal MRI to study the GE, it becomes possible to detect these disruptions early in gestation, potentially allowing for timely interventions and better parental counseling. Read More

HNF1B nephropathy is a hereditary renal disease caused by mutations in the HNF1B gene, transmitted in an autosomal dominant manner but frequently occurring as de novo mutations. This genetic variability complicates diagnosis, as family history of renal disease may be absent. Clinical presentation is heterogeneous, with onset in both children and adults, and may include renal dysfunction, metabolic abnormalities, and in some cases early-onset diabetes. In the pediatric setting, imaging plays a crucial role in raising suspicion of HNF1B nephropathy. Prenatal ultrasound and MRI may reveal echogenic kidneys or renal hypoplasia in the third trimester, while postnatal ultrasound may show variable findings such as increased renal echogenicity, renal cysts, and reduced renal size. These abnormalities can mimic more common entities, highlighting the importance of a systematic imaging approach. This educational exhibit reviews the prenatal and postnatal imaging findings of HNF1B nephropathy in children emphasizing key imaging clues that should raise diagnostic suspicion when encountering cystic or dysplastic renal patterns. The exhibit also includes discussion of the differential diagnosis with other conditions associated with renal cysts, such as autosomal dominant polycystic kidney disease (ADPKD), autosomal recessive polycystic kidney disease (ARPKD), multicystic renal dysplasia, Meckel–Gruber syndrome and other ciliopathies. Recognizing the imaging spectrum of HNF1B nephropathy is essential to avoid misclassification as nonspecific chronic interstitial nephropathy and to ensure timely genetic testing, counseling, and long-term multidisciplinary management.
