Chylous mesenteric cyst: A diagnostic dilemma

A mesenteric cyst is defined as a cyst that is located in the mesentery of the gastrointestinal tract and may extend from the base of the mesentery into the retroperito- neum. A case report of a patient with mesenteric cyst is presented. In addition, a systematic review was performed of English language literature on chylous mesenteric cysts in adult hu- mans. Of the 18 articles included in the review, there were 19 cases of chylous mesenteric cysts reported. Male to female ratio was 1.4:1 with a median age of 46 years. A preoperative diagnosis of mesenteric cyst was made in four patients based on computed to- mography. All patients underwent surgery and there were no reports of recurrence on follow up. Chylous mesenteric cyst is a rare entity that needs to be recognized whenever a prelimi- nary diagnosis of intra-abdominal cystic mass is made.
