Mesenteric chylous cyst associated with Crohn's disease.

Mesenteric cysts are rare, and mesenteric chylous cysts are extremely rare. A case report is presented of a patient with Crohn's disease and a mesenteric chylous cyst. Included in this case report is a full discussion of the preoperative radiological work-up (including barium enema, sonogram, and CT scan), the operative findings, and the pathological findings. It is suggested that there may be a causal relationship between the Crohn's disease and the mesenteric chylous cyst.
