Lipoma With Inverted Meckel's Diverticulum Causing Intestinal Intussusception and Anemia: Report of a Case.

Meckel's diverticulum (M.D.) is the most frequent congenital anomaly of the gastrointestinal tract. Inverted Meckel's diverticulum is a rare clinical condition, and intussusception caused by M.D. inversion is even more uncommon. We present a case report of an inverted Meckel's diverticulum with associated lipoma as a cause of unexplained anemia and acute intestinal obstruction in a young man, and a brief literature review. The patient presented to the emergency room with acute abdomen. A computed tomography (CT) scan revealed ileo-ileal intussusception with a suspected intraluminal lipoma. Surgical resection of the intussuscepted ileal segment was performed, with an uneventful postoperative course. Histopathology showed an inverted Meckel's diverticulum with a lipoma associated. Inversion of a Meckel Diverticulum with an associated lipoma causing intussusception is extremely uncommon, and emergency abdominal surgeon could face it in differential diagnosis and treatment of acute abdomen. Surgical resection with primary anastomosis is the treatment of choice of this rare finding, with a high percentage of good results.
