Abstract
A 44-year-old woman was admitted to our hospital because of abdominal pain. Abdominal radiographic and CT scans showed enlarged colon with a mesenteric tumor. Barium enema revealed colon enlargement due to duplication of the transverse colon. Laparotomy was performed, and the duplicated colon was resected along with the mesenteric tumor. The mesenteric tumor was diagnosed as dermoid cyst on the basis of histological findings.
Intestinal duplication is a rare congenital anomaly that is usually diagnosed during childhood. However, in rare cases, the condition may remain undiagnosed until adulthood. The mesentery is an unusual site for development of a dermoid cyst. Here, we report an extremely rare case of duplication of the transverse colon with a mesenteric dermoid cyst in an adult patient.
