ABSTRACT
Colovesical fistula is not an infrequent urologic complication of diverticulitis. However, the frequency of diverticuli at sigmoid colon is low in Korea, and there have been few radiologic reports of colovesical fistula caused by diverticulitis. We report a case of colovesical fistula secondary to sigmoid diverticulitis that mimics bladder tumor on ultrasonography. Additional diagnostic modalities including CT and MRI were performed, and pathologic confirmation was done by surgery.
