Emergency abdominal CT showed air in the hepatic portal veins (Fig. 1), focal dilatation of the small bowel with wall thickening, mesenteric fat stranding and peritoneal fluid collection, free air in the retroperitoneum, mainly to the right (retroperitoneum) (Fig. 2), air in the peritoneal cavity, mainly in the lower pelvic area, and free air in the pararectal space (Fig. 3). Moreover, pleural effusion and atelectasis was found in both lower lobes of the lungs (Fig. 1).     
Abdominal CT scan demonstrates: (i) pneumatosis intestinalis in rectum and free air in the pararectal space; (ii) pneumatosis intestinalis in sigmoid colon; and (iii) free air in lower pelvis in contact with the right inguinal canal.
