title: Postoperative pelvic gas collections simulating pelvic abscess.
abstract: Extraperitoneal gas collections are routinely found in pelvic soft tissues following abdominal hysterectomy. These collections have the typical appearance of extraperitoneal gas but should not be confused with pelvic infection or bowel injury. Similar collections are not routinely found following vaginal hysterectomy.
