Duplication cyst of the bowel causing ileal volvulus. A case report.

A 10 month old male infant presents to us with features of acute intestinal obstruction and a palpable abdominal mass of five days duration. A prior ultrasound report had made a diagnosis of intussusception. Subtle but important details in history and examination cast doubts on the ultrasound diagnosis. Exploratory laparotomy revealed ileal volvulus secondary to duplication cyst. This case is reported because of its rarity and to show the strength of sound clinical evaluation even in the face of technological advancements.
