Arterial phase Contrast enhanced axial CT with remarkable PI and pronounced mesenteric gas (A, B) in a 73-year-old patient without intestinal necrosis or ischemia. C, D are illustrating (magnified) the intestinal segments the yellow arrows in A and B are pointing at but in a lung window to emphasize the extent and localization of the gas. PI was fully reversible upon seven-day follow-up non contrast enhanced axial CT (E, F). As the patient was receiving chemotherapy for cancer of the hypopharynx, this may be a case of drug-related reversible/ “benign” PI. The patients’ medical history was also remarkable for hypertension and COPD
