title: Pneumatosis intestinalis and portal-venous gas: an unusual presentation of acute appendicitis.
abstract: Pneumatosis Intestinalis in association with portal venous gas is a very rare finding in children and young adults. When present, it is typically associated with bowel infarction and carries a poor prognosis. We present an extremely unusual case where imaging revealed extensive pneumatosis intestinalis and portal venous gas in a patient with acute appendicitis.
