Ischemic colitis is similar to type 4 of colonic cancer on the macroscopical findings and the differential diagnosis is very difficult.
A 66-year-old woman visited our hospital with complaints of lower abdominal pain and bloody stool. Barium enema and colonoscopy revealed a stenotic lesion with shallow ulcer in the sigmoid colon.
CF-EUS findings showed thickness of the colonic wall and hypoechoic changes with unclearness of boundary form from the first to fourth layer. But boundary form was not destructed. Histological findings of colonic mucosa showed non-specific chronic inflammatory changes and malignant cell was not found. We finally diagnosed as ischemic colitis and denied colonic cancer.
CF-EUS was useful for differential diagnosis of ischemic colitis from other malignant disease showing stenosis, such as type 4 of colonic cancer.
