title: 'Benign' hepatic portal venous gas.
abstract: The presence of portal venous gas within the hepatic parenchyma is usually associated with a guarded prognosis and a mortality rate approaching 75%. However, there are infrequent causes of portal venous gas not associated with dire clinical outcomes. We describe three patients who made uneventful clinical recoveries after presenting with clinical and imaging manifestations of ischaemic bowel and hepatic portal venous gas, two of which had distended but non-necrotic bowel at laparotomy.
