From: Acute abdominal pain in women of reproductive age: keys to suggest a complication of endometriosis
39-year-old female presenting with acute abdominal pain and abdominal tenderness at physical examination. Axial enhanced CT (a, b) shows findings of acute peritonitis: pneumoperitoneum (circles), peritoneal effusion (circles), peritoneal thickening, and fecal material within the peritoneal cavity (star). The presence of fecal material close to the sigmoid colon is suggestive of the site of perforation (a). A stenosis of the sigmoid is suspected (arrows, (b)). The patient had a history of shaving surgery for rectosigmoid endometriosis and had a pelvic MRI a few weeks before. T2W MRI (c, d) confirms the presence of a fibrotic stenosis of the sigmoid (arrows), most probably secondary to shaving surgery
