Rare Variant of Meckel’s Diverticulum on the Mesenteric Border Complicated by Perforation: Case Report and Literature Review

Background: Meckle’s Diverticulum (MD) is a remnant of vitello intestinal duct found in approximately 2-4% of normal population and is usually located on the anti-mesenteric border of terminal ileum. Its variant, the mesenteric type is even rarer, with only a few cases reported in literature.Case: We describe a case of inflamed mesenteric MD that presented with clinical findings of acute appendicitis, but, upon exploration, was diagnosed as inflamed mesenteric MD, that was removed, and the patient recovered without any complications and went home in good condition. We also review all the mesenteric MD cases reported in the literature since 1941.Conclusion: MD is a rare operative finding, but knowledge of its rare variant must be kept in mind as the signs and symptoms closely resemble acute appendicitis.
