[Intestinal pneumatosis].

Intestinal pneumatosis is an infrequent disease of difficult clinical and radiologic diagnosis. It may be accompanied by pneumoperitoneum in up to 30% of the cases leading to differential diagnosis with pictures of visceral perforation. We herein present 4 cases of intestinal pneumatosis in whom pneumoperitoneum was associated in 3 patients. Diagnosis was intraoperative in 2 patients submitted to emergency surgery because of an associated acute gastrointestinal event (intestinal volvulus and acute cholecystitis). The other 2 cases were diagnosed by computerized tomography and colonoscopy, respectively, and given their satisfactory clinical evolution they received conservative treatment. The course of the disease was favorable in all the patients with the radiologic signs of pneumatosis disappearing.
