A case of hepatic portal venous gas due to viral gastroenteritis.
BACKGROUND
Hepatic portal venous gas is the presence of gas within the portal venous system that can result from a variety of insults to the gastrointestinal system, and which may be a diagnostic clue to ominous abdominal pathologies, such as acute bowel ischemia or necrosis.


METHODS
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.


CONCLUSIONS
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.
