A case of retroperitoneal abscess: A rare complication of Meckel's diverticulum.

INTRODUCTION: The frequent complications of Meckel's diverticulum are hemorrhage, intestinal obstruction, and inflammation, and perforation. The presentation as a retroperitoneal abscess as complications of Meckel's diverticulum is a very rare clinical entity.

PRESENTATION OF CASE: We report a rare case of perforated Meckel's diverticulum with retroperitoneal abscess. A 31-year-old presented with a half-hour history of severe epigastric pain and diffuse periumbilical pain. Abdominal computed tomography (CT) revealed pneumoperitoneum and retroperitoneal abscesses which air, with diffuse infiltration of the small bowel mesentery and a tubular structure that originated in the ileum at the umbilicus level. Preoperative diagnosis was perforation of Meckel's diverticulum or small bowel perforation. We performed an approximate 10-cm segmental resection of the ileum that contained the Meckel's diverticulum.

DISCUSSION: Retroperitoneal abscesses are rare complications of Meckel's diverticulum and are associated with its perforation.

CONCLUSION: The complications of Meckel's diverticulum should be kept in mind in the differential diagnosis of retroperitoneal abscesses.
