摘要
目的 探讨肝脏淋巴瘤的CT及MRI特点。方法 回顾性分析2011年1月至2018年3月首都医科大学附属北京友谊医院收治的10例肝脏淋巴瘤患者的临床(肿瘤标志物、肝脏生化指标)及影像学资料(病灶的密度、信号特点、强化方式、血管情况等)。结果 10例肝脏淋巴瘤患者中,继发性7例,原发性3例;多发结节型5例,结节密度/信号均匀,可见渐进性强化;单发肿块型3例,2例出现靶环样结构;浸润型2例,边界不清,渐进性强化。7例可见病灶内血管穿行而无明显受侵征象。结论 肝脏淋巴瘤影像学表现多样,实性部分密度或信号均匀,呈渐进性强化,病灶内血管穿行对诊断有提示价值;特征性靶环样结构-周边均质的实性部分伴中心纤维结构及最外周包膜,对肝脏原发性淋巴瘤的诊断有提示意义。
Objective To investigate the CT and MRI features of hepatic lymphoma. Methods The clinical and imaging data of 10 patients in Beijing Friendship Hospital from January 2011 to March 2018 with hepatic lymphoma were analyzed retrospectively. Results Ten patients with hepatic lymphoma, 7 cases were secondary hepatic lymphoma and 3 cases were primary lymphoma. Five cases were multiple nodules type with homogeneous density or signal and showed progressive enhancement. Three cases were solitary nodule type with two cases showing target ring sign. Two cases were infiltrative type with unclear boundary and progressive enhancement. In 7 cases, the presence of vascular encasement by a periportal hepatic mass without vascular occlusion or thrombosis were presented. Conclusion The imaging manifestations of hepatic lymphoma were various. The density or intensity of the mass was homogeneous and most of them show progressive enhancement. Vascular penetration in the lesion without invasion was a pointer toward hepatic lymphoma. Characteristic target ring structure with homogeneous solid tumor tissue and central fibrous structure and peripheral capsule may be helpful in the diagnosis of liver primary lymphoma.
