Case: We report a case of a 71-year-old man with acute onset abdominal pain whose initial radiologic testing showed extensive portal venous gas. The patient was managed conservatively with resolution of portal venous gas on day 2 of hospitalization. The findings were consistent with a final diagnosis of hepatic portal venous gas caused by viral gastroenteritis. Conclusion: History and physical examination along with presenting signs and symptoms, in conjunction with imaging studies, are vital to delineate the cause of hepatic portal venous gas. In the absence of alarming signs and symptoms, hepatic portal venous gas can be conservatively managed without the need for invasive surgical exploration.
