title: Meckel's diverticulum: axial volvulus mimicking emphysematous cholecystitis.
abstract: A 48-year-old man presented with symptoms of acute cholecystitis. Abdominal roentgenograms suggested emphysematous cholecystitis. Axial volvulus of a Meckel's diverticulum was discovered at surgery. We discuss this unusual complication of Meckel's diverticula as well as the roentgenographic differential diagnosis of air in the gallbladder.
