The radiographic finding of gas at the periphery of the liver, extending within 2 cm of the capsule of the liver, indicates that the gas is in the portal system. Hepatic portal venous gas is most frequently associated with necrotic bowel. The mortality rate of patients with this finding is very high. This finding of branching radiolucency signifies that the patient's condition warrants emergency surgery.
