A computed tomography (CT) scan demonstrated no evidence of an acute intra-abdominal disturbance (Figure 1). An extensive amount of gas, however, was found in the portal venous system (Figure 1).
Repeat computed tomography scan (3 hours later) with oral contrast showing resolution of hepatic portal venous gas.

Although the results reflected a diminished amount of portal venous gas, there was no evidence of any acute abdominal pathology that may have caused the hepatic portal venous gas (Figure 2).
