Intestinal Obstruction from Congenital Bands at the Proximal Jejunum: A Case Report and Literature Review

Congenital anomalous bands at the proximal jejunum resulting in obstruction have been described sporadically in the literature and are otherwise rare. We present a case of an 8 year-old girl with a nine-month history of intermittent vomiting and no history of prior surgery. The imaging workup includes an abdominal ultrasound, a single contrast upper gastrointestinal series, and a dual contrast computed tomography of the abdomen and pelvis. Surgical intervention revealed the presence of dense bands at the proximal jejunum without evidence of malrotation. Our report reviews the embryology and radiologic findings of this entity using different imaging modalities.
