原发性肝脏恶性纤维组织细胞瘤的CT表现

目的：分析探讨肝脏恶性纤维组织细胞瘤（MFH）的CT表现,提高对该病的认识。方法：回顾性分析3例经手术病理证实的肝脏MFH的CT及临床资料。3例患者均行上腹部CT平扫、三期动态增强扫描。结果：3例肝脏MFH体积均较大,2例表现为边界尚清晰的单发肿块,1例为边界不清的弥漫性多发瘤灶;瘤内均有不同程度的囊变坏死,无钙化;增强扫描可表现为延迟强化（2例）或快进慢出（1例）;1例伴胆管扩张及胆管癌栓。3例均无门静脉癌栓、淋巴结及远处转移。结论：肝脏MFH的CT表现形式多样,临床最终诊断依赖病理,特别需与原发性肝细胞癌或胆管细胞癌鉴别。

Primary malignant fibrous histiocytoma of the liver:a CT study

Objective:To describe and analyze CT appearances of primary hepatic malignant fibrous histiocytoma(MFH) of the liver.Methods:A retrospective analysis of clinical data and multiphase dynamic CT images was performed in 3 patients with pathologically proven hepatic MFH.Results:Of the 3 patients,all 3 presented with large masses,2 had solitary,relatively well-defined tumors,and 1 had ill-defined infiltrative lesions.Varying degrees of cystic or necrotic changes were seen within all the tumors,but no calcificati...
