title: Retrocecal appendicitis presenting with air in the subhepatic space.
abstract: Two cases of perforated retrocecal appendicitis presenting with the roentgen finding of an air containing subhepatic abscess are discussed. Although it is an unusual cause for air in the right subhepatic space, retrocecal appendicitis should be considered in the radiologist's differential diagnosis.
