[Two cases of liver scar that was examined by biliary scintigraphy]

36-year-old-female admitted because of jaudice and ascites. T-bil was 18.5 mg/dl and transaminase, ALP, LDH and gamma-GTP was elevated. Ultrasonography (US) showed that right lobe was atrophy and left lobe was swelling. Plain computed tomography (CT) showed right lobe was low density. Magnetic resonance (MR) finding was T1-weighted image of right lobe was low intensity and T2-weighted image was high intensity. Angiography showed right lobe was more stained than left lobe. Histologically, right lobe was massive necrosis. These findings suggested that right lobe was liver scar. Biliary imaging showed right lobe was delayed. A 23-year-old-female admitted because of fever and abdominal tumor. Transaminase was normal, only gamma-GTP was elevated. US, plain CT, enhanced CT, MR imaging finding was as same as that of the first case. Similarily, biliary scintigraphy showed right lobe was delayed. Causes of the two liver scars was not clear, whereas liver scar detected after delivery was rare case.
