| 概要 | 36-year-old-female admitted because of jaudice and ascites. T-bil was 18.5 mg/dl and transaminase, ALP, LDH and γ-GTP was elavated. Ultrasonography (US) showed that right lobe was atrophy and left lob...e 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 γ-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. 妊娠, 分娩を契機に発見された瘢痕肝2例を経験した. 症例1は35歳女性. 分娩約2カ月後に腹水, 黄疸を伴った急性肝障害にて入院. 肝庇護剤, 利尿剤などの使用にて軽快した. 症例2は23歳女性. 分娩約2カ月後に発熱, 右腹部腫瘤を認め入院. 両症例とも単純CTで肝右葉は低濃度, 造影CTでは正常肝と同程度に造影され, 腹部MRIのT1強調像では肝右葉は低吸収, T2強調像では高吸収域を示し, 画像上瘢痕肝として特徴的な所見を呈した. 胆道シンチでは瘢痕部における排泄障害を認めた. 両症例とも瘢痕肝をきたした肝壊死についての原因は明らかにできなかった.続きを見る |
