Gastric volvulus through a Morgagni hernia: multidetector computed tomography diagnosis.

Hernia through the foramen of Morgagni (HM) is uncommon in adults, accounting for only 3% of all treated diaphragmatic hernias. We report a very rare case of acute gastric volvulus producing within this type of hernia. It was found in an 81-year-old man presenting with symptoms of acute gastric outlet obstruction. The diagnosis was first suspected on plain abdominal and chest radiographs, but a safe and complete anatomic preoperative diagnosis was clearly achieved with multidetector computed tomography (MDCT). The paper refers to the basic anatomy, clinical symptoms, diagnostic, and therapeutic considerations for HM and emphasizes the major advantages of MDCT in acute surgical conditions implicating the thoracic abdominal junction.
