摘要 目的:评价原发性肝脏淋巴瘤的螺旋CT和MRI表现。方法:回顾性分析经病理证实的8例原发性肝脏淋巴瘤的螺旋CT和MRI表现,包括平扫和动态增强动脉期和门脉期的图像,评价病灶的部位、大小、形态、与邻近结构的关系、腹部其他脏器的表现。结果:非霍奇金淋巴瘤7例,霍奇金淋巴瘤1例。所有患者肝脏无肝硬化表现,病灶均为肝内单发结节灶,CT平扫呈均匀低密度,边缘模糊,动态增强后动脉期病灶为轻-中度强化,门静脉期病灶轮廓勾画得最清楚,未见大片坏死区域,在MRI上病灶呈长T1长T2信号,动态增强方式类似于CT表现,1例病灶可见假包膜,所有患者脾脏均未见肿大,胆道无扩张,血管未见受侵犯。结论:原发性肝脏淋巴瘤在螺旋CT和MRI上有一定特征性,能够指导临床进一步诊疗计划的制定。
