Wandering spleen causing splenic flexure volvulus and obstruction.

A 48-year-old woman presented with symptoms of distal bowel obstruction. On examination she had abdominal distension and a lump in the left lumbar and iliac regions. X-ray revealed distension of the colon with dilated small bowel. Exploration revealed an enlarged ptotic spleen whose pedicle caused obstruction of the colon. There was concomitant partial volvulus of the splenic flexure around the splenic pedicle. The splenic vein was thrombosed. Splenectomy was performed.
