原发恶性纤维组织细胞瘤(MFH)是一种独特的肿瘤,可累及深部筋膜、四肢骨骼肌或腹膜后腔。它极少起源于肝脏,其MRI表现尚未有过报道。作者报道1例经病理组织学证实的肝脏原发MFH。男性,52岁。CT增强扫描证实肝右叶一巨大不均质肿块,内含大量液性密度成份,有多发分隔及壁结节,肿块无对比强化。动脉造影及肝静脉造影显示一个乏血管肿块压迫肝动脉及肝静脉。MRT
Primary malignant fibrous histiocytoma (MFH) is a unique tumor that can affect the deep fascia, skeletal muscles of the extremities, or the retroperitoneum. It rarely originates in the liver and its MRI performance has not been reported. The authors reported a case of liver primary MFH confirmed by histopathology. Male, 52 years old. CT-enhanced scans confirmed a large heterogeneous mass in the right lobe of the liver, containing a large number of fluid-density components, multiple divisions and mural nodules, and no contrast enhancement of the mass. Arteriography and hepatic vein angiography showed that a vascular plexus oppresses the hepatic artery and hepatic vein. MRT
