[Usefulness of 111In labeled leukocytes scintigraphy combined with 99mTc phytate liver scintigraphy for diagnosis of hepatic abscess comparing with CT and US].
111In labelled leukocyte scintigraphy (ILLS) was performed in five patients with hepatic abscess. For the accurate diagnosis of hepatic abscess, ILLS was superimposed on 99mTc phytate liver scintigraphy. The results of ILLS were compared with CT and US findings. Four of five patients (80%) showed abnormal accumulations in the liver. The smallest abscess detected was 46 mm x 43 mm. CT scan showed rim enhancement, which was a specific finding for hepatic abscess, in three patients. It was rather difficult to diagnose hepatic abscess by US. In two cases without definite rim enhancement on CT, the abscesses were diagnosed as hot spots by ILLS. We conclude that ILLS combined with 99mTc liver scintigraphy is useful for the diagnosis of hepatic abscess.
