[Clinical Picture] Extremely large air distension of the bowel
A 14-year-old girl presented to our paediatric department in May, 2012, with massive abdominal distension that had developed over the previous 2 years. She reported chronic abdominal discomfort, alternating diarrhoea and constipation, and two previous subocclusive episodes that had resolved with laxative therapy. Plain abdominal radiographs showed substantial large bowel distension and several air–fluid levels. No air was evident in the rectum or anal canal (figure).
