Blood infection with enterobacter aerogenes - an unusual cause of portal vein gas.
J Pak Med Assoc Jan ;61(1):88-90.

Portal vein gas was once thought of as an invariably fatal condition. Now, with the availability of better equipment and expertise, the condition is more frequently diagnosed. A case of fever with rigors is presented and on ultrasound and CT examination was found to have portal venous gas which resolved with adequate antibiotic treatment. Blood culture revealed growth of gram negative bacillus; Enterobacter aerogenes. Patient was investigated further for portal vein gas, and although no other cause for the development of portal vein gas was found, she was treated with antibiotics and showed an immediate response. The aim of this case report is to highlight the benign causes of portal vein gas as well as to discuss the causes which warrant immediate surgery. Portal vein gas may herald a more ominous condition, which if intercepted in its course may result in complete cure.
