Supravesical hernia: CT diagnosis.

We report two cases of surgically proven supravesical hernia, one an internal supravesical hernia and the other an external supravesical hernia. Abdominal computed tomography showed the relation of the incarcerated intestine anterior to and compressing the urinary bladder. Although neither case was diagnosable preoperatively, we believe that the preoperative diagnosis of supravesical hernia by abdominal computed tomography is possible.
