Abstract： 目的分析5例不同组织类型的肝脏少见恶性肿瘤的CT表现,以提高对这些恶性肿瘤的识别能力.方法经临床和病理证实的肝脏少见恶性肿瘤5例,均行CT检查,其中肝肉瘤3例(包括血管肉瘤1例,恶性间叶瘤1例,恶性纤维组织细胞瘤1例,类癌2例).结果上述肝脏恶性肿瘤表现多样化,恶性间叶瘤以儿童肝内巨大单发囊性为主病灶;肝血管肉瘤表现为肝内多发境界清楚的低密度灶,可合并坏死、囊变及新鲜出血,无肝硬化基础;恶性纤维组织细胞瘤为肝右叶单发巨块低密度病灶,可伴纤维分隔,免疫组织化学标记具有诊断价值;类癌CT特征为肝内单发或多发病灶,密度不均匀,呈单房或多房,增强表现实质部分强化,伴类癌综合征时更具有诊断价值.结论本组分析的5例肝脏恶性肿瘤临床均较少见,各种病理类型的此类肿瘤有其相似和不同的CT征象,结合临床及实验室检查,应在临床诊断中考虑到上述肿瘤的可能,以免漏诊或误诊.
