OBJECTIVE
The MR findings in two cases of primary lymphoma of the liver (PLL) are presented.
MATERIALS AND METHODS
MR of two cases of primary lymphoma of the liver were reviewed and its features were estimated.
RESULTS
Both cases showed a solitary large liver mass. On T1-weighted imaging the tumor was isointense in one and homogeneously hypointense to the liver parenchyma in the other. On T2-weighted imaging both tumors were homogeneously hyperintense. In one case the margin of the tumor was poorly defined, and portal branches were identified within the tumor, an unusual finding in other liver neoplasms.
CONCLUSION
In patients with liver masses with homogeneous intensity on MR but without liver dysfunction and other malignancies, PLL should be included in the differential diagnosis.
目的
介绍两例原发性肝脏淋巴瘤（PLL）的磁共振成像（MR）表现。
材料与方法
回顾两例原发性肝脏淋巴瘤的MR图像并评估其特征。
结果
两例均表现为肝脏单发大肿块。在T1加权成像中，一例肿瘤呈等信号，另一例相对于肝实质呈均匀低信号。在T2加权成像中，两例肿瘤均呈均匀高信号。其中一例肿瘤边界不清，在肿瘤内可见门静脉分支，这在其他肝脏肿瘤中不常见。
结论
对于肝脏肿块在MR上呈均匀信号强度、无肝功能障碍及其他恶性肿瘤的患者，鉴别诊断时应考虑原发性肝脏淋巴瘤。
