摘要 目的探讨原发性脑淋巴瘤MRI主要表现和特征,以及病理学基础。方法收集经手术、病理和免疫组化证实,资料齐全的原发性中枢神经系统淋巴瘤病患者30例,分析其MRI表现,以及病理学资料。结果 B细胞来源的22例,多为LCA、CD20、CD79阳性;T细胞来源的8例,多为LCA、CD45RO、CD3阳性;肿瘤形态多为类圆形肿块或结节,瘤周水肿多为轻至中度水肿。MRI平扫显示病灶T1WI多呈等、低信号,T2WI多呈等、高信号,FLAIR呈稍高或高信号,增强后病灶呈明显均匀信号,形态为多发节结状、团块状,边缘多有"棘状"突起及分叶。结论原发性脑淋巴瘤病理学基础决定其MRI表现特征,结合临床表现,可以对其做出正确诊断。
