Liver scan showing intense lung uptake in neoplasia and infection.

Two cases of intense lung activity uptake during routine liver imaging are presented. One patient died 6 days after uptake was seen, and had Kupffer cell tumor, or liver angiosarcoma, at autopsy. The second patient with an acute infection superimposed on alcholic hepatitis showed intense lung uptake on the tenth day of a sustained course of very high fever. A repeat liver scan after the patient became afebrile showed no lung uptake.
