title: Computerized tomography in the diagnosis of appendicovesical fistula.
abstract: Appendicitis and its complications are among the causes of an enterovesical fistula, with approximately 100 such cases reported. This condition is seldom diagnosed preoperatively and surgery is often delayed. We report 2 cases of an appendicovesical fistula that were diagnosed preoperatively by computerized tomography (CT). We describe a CT finding consistent with the diagnosis, namely calcification in the thickened bladder wall adjacent to the cecum on noncontrast CT, which is a fecalith in the lumen of the fistula.
