From: Pneumatosis intestinalis leading to perioperative hypovolemic shock: Case report
CT. Abdominal CT reveals diffuse intramural gas from the ascending colon to the transverse colon and a large amount of free air in the abdominal cavity without portal venous air or extraluminal fluid collections. This study shows diffuse pneumoperitoneum, which led us to suspect the presence of gastrointestinal perforation. Portal venous gas, which frequently follows severe pneumatosis intestinalis, is also absent.
