ischemic colitis

ischemic colitis
a type of colitis caused by acute vascular insufficiency of the colon, usually the part supplied by the inferior mesenteric artery; symptoms include pain at the left iliac fossa, bloody diarrhea, low-grade fever, abdominal distention and tenderness, and sometimes ulceration. Radiologically there is “thumbprinting” due to localized elevation of the mucosa by submucosal hemorrhage or edema.
