title: Perforated Meckel's diverticulitis on the mesenteric side: MDCT findings.
abstract: Meckel's diverticulum (MD) is the most common congenital anomaly of the gastro-intestinal tract (approximately 2% of population), and arises from improper closure and absorption of the omphalomesenteric duct. Very few cases of Meckel's diverticulitis on the mesenteric side have been reported in the surgical literature, and no reported cases have been documented on preoperative imaging. We report a 65-year-old woman presenting symptoms and signs of acute abdomen with an initial suspicion of acute appendicitis. MDCT imaging revealed a mesenteric abscess in the right lower quadrant at the level of the distal ileum as a complication of Meckel's diverticulitis on the mesenteric side. The patient recovered after a diverticulectomy without the need for a small bowel resection. This case demonstrates that MDCT is a fast imaging technique that may be helpful in the emergency setting for the preoperative diagnosis of an unusual complicated MD on the mesenteric side.
