Adult with intestinal malrotation and colocolic intussusception: an unusual combo. Intestinal malrotation is a congenital anomaly that results from an abnormality in the rotation and fixation of the gut as it returns to the abdominal cavity during development. Intussusception is a condition characterised by telescoping of one segment of the bowel into another segment. The combination of malrotation and intussusception is frequently a cause of intestinal obstruction in the paediatric age group. The coexistence of these two conditions is termed as Waugh syndrome and is uncommon in adults. We share our experience with an elderly woman who was admitted with diarrhoea and anaemia. Investigations revealed a large colonic polyp, colocolic intussusception and malrotation. The adenomatous polyp and mobile right colon would have lead to intussusception. The diagnosis was based on the findings of colonoscopy and contrast-enhanced CT scan of the abdomen. She was managed with a transverse colectomy with an uneventful recovery.
