From: Pneumatosis intestinalis versus pseudo-pneumatosis: review of CT findings and differentiation
Intramural and portomensenteric venous gas in a 66-year-old asymptomatic man after duodenal ulcer repair. a Axial unenhanced CT shows diffuse, bubble-like and curvilinear intramural gas collections (arrows) throughout the small bowel, consistent with pneumatosis intestinalis. b, c Axial CT images at two different abdominal levels show diffuse branching lucency in the mesenteric vessels (arrow, b) and the periphery of the liver indicating portal vein gas (arrow, c). d Axial unenhanced CT, acquired at the same level as a after 10Â days of follow-up, shows complete resolution of pneumatosis intestinalis following a benign clinical course
