Isolated Superior Mesenteric Artery Vasculitis as a Cause of Abdominal Pain.

This manuscript demonstrates that although isolated superior mesenteric artery vasculitis that also could be called as localized vasculitis of the gastrointestinal tract was rare entity, it is so significant as differential diagnosis of abdominal pain in addition to idiopathic dissection, infective arteritis, and lymphoma. This case should remind readers to consider isolated superior mesenteric artery vasculitis as a cause of (upper) abdominal pain.
