title: Internal abdominal hernia: diagnosis with ultrasonography.
abstract: The imaging findings associated with internal abdominal hernia have been reported for plain radiography, barium studies, arteriography and computed tomography. The authors present a case in which the ultrasonographic findings indicated left paraduodenal hernia. In the investigation of an abdominal mass, the presence of changing cystic or tubular internal components and a surrounding membrane should arouse suspicion of an internal hernia.
