Figure 3. Contrast-enhanced abdominal computed tomography findings associated with the patient’s third episode of abdominal pain. (A) Low-density areas with air density in the portal veins are widely observed in both hepatic lobes, including in the right posterior segment (arrowheads). A water density area suggests a considerable amount of ascites (dashed arrow). (B, C) Linear low-density areas in the intestinal wall indicate the presence of linear pneumatosis intestinalis (arrows), resulting in the demise of the patient. (D) An enlarged view of Figure C shows the linear appearance of gas in the intestinal wall in greater detail (arrow).
