[A woman with abdominal pain and retroperitoneal free air]. / Een vrouw met buikpijn en retroperitoneaal vrij lucht.

ABSTRACT

A 62-year-old female was admitted to the hospital with pain in the lower abdomen and fever since 1 week. A CT scan showed retroperitoneal air around the inferior mesenteric vein and diverticulitis of the sigmoid. We made the diagnosis of intramesocolic diverticular perforation of the sigmoid, a rare phenomenon, and performed an emergency sigmoidectomy.
