[Mesenteric cyst in the descending colon: a case report].

Mesenteric cysts are rare abdominal findings. The majority are asymptomatic and if found are discovered incidentally during ultrasonography and/or CT scanning. The optimal surgical treatment requires complete excision of the cyst. We report a case of 36-year-old woman with mesenteric cyst in the descending colon. Laboratory tests indicated no abnormality. Abdominal CT revealed a cystic mass in the retropreritneal space measuring 14.0 x 8.3 x 9.4 cm, density 26-29 HU. We found a cystic mass at the mesentery of the descending colon that was removed in toto. The authors discuss the symptoms and complications, classification, and treatment of mesenteric cysts with review of literature.
