[A case of internal supravesical hernia].

We report a case of internal supravesical hernia. A 74-year-old male with complaint of abdominal pain underwent an operation for small intestinal obstruction due to its incarceration into the internal supravesical hernia. Retrospectively, the preoperative abdominal CT film showed the relation of the incarcerated intestine, the urinary bladder, and the middle umbilical ligament. This is the first case of the internal supravesical hernia in which the preoperative CT had taken and it will contribute to the preoperative correct diagnosis in the future.
