COMBINED OCCURRENCE OF RETROPNEUMOPERITONEUM AND PNEUMOPERITONEUM

Abstract
A combined occurrence of massive retropneumoperitoneum and pneumoperitoneum is rare. Two recent cases are reported: one resulting from an iatrogenic perforation of the sigmoid; and the other from an inadvertent introduction of air into the retroperitoneal space. The anatomic relationships, directions of spread, and the roentgen manifestations of a combined occurrence of retropneumoperitoneum and pneumoperitoneum are discussed.
