Small bowel internal hernia and sigmoid volvulus through a congenital mesenteric defect

An 11-month-old male infant WHO presented with excessive crying and constipation of five days duration developed vomiting after admission. Physical examination revealed an irritable baby with a distended abdomen and digital rectal examination revealed an empty rectum. The abdominal radiograph showed bowel filled with feces and the ultrasound showed dilated large bowel loops filled with feces and fluid. In view of the inconclusive nature of these reports, an abdominal computed tomography (CT) was done which revealed dilatation of the proximal large bowel proximal to the sigmoid colon along with dilated proximal small bowel loops.
