Abstract

Two cases of iron overload in the liver are presented--one of hemochromatosis with associated hepatoma and one of hemosiderosis with probable androgen dependent multicentric hepatic adenomas. Nuclear magnetic resonance scans displayed the tumours as well as low liver parenchymal signal intensity on the saturation-recovery, inversion-recovery, and spin-echo pulse sequences probably as a result of decreased tissue T1 and T2.

摘要

本文报告了两例肝脏铁过载病例——一例为血色素沉着症合并肝癌，另一例为含铁血黄素沉着症，可能伴有雄激素依赖的多中心肝腺瘤。核磁共振扫描显示，在饱和恢复、反转恢复和自旋回波脉冲序列上，肿瘤以及肝实质信号强度较低，这可能是由于组织T1和T2降低所致。
