Mesenteric lipodystrophy of the left colon.

Mesenteric lipodystrophy is a rare condition characterized by tumor-like expansion of the mesocolon. The etiology remains obscure, but autoimmunity, abdominal trauma, abdominal surgery, and ischemic injury have all been postulated. To our knowledge, there have been no previous reports of synchronous mesenteric lipodystrophy and angiodysplasia. Whether these are independent or associate entities remains unknown. We present the clinical, radiological, and pathological findings of such a case.
