摘 要: | 目的研究原发性中枢神经系统淋巴瘤的MRI表现。方法回顾性分析7例PCNSL患者的MRI表现。结果单发病灶4例,多发病灶3例,共11个病灶,其中分布于额叶4个,顶叶、颞叶、小脑半球各2个,胼胝体1个。T1WI呈低或稍低信号,T2WI呈高信号或稍高信号,FLAIR呈高信号或稍高信号,DWI高信号。增强扫描病灶明显均匀强化,可见"缺口征"(2个)和"尖角征"(1个),3个病灶邻近脑膜可见异常强化。伴囊变坏死5个,出血2个。轻-中度水肿8个,重度水肿3个。结论原发性中枢神经系统淋巴瘤的MRI表现有一定的特征性,但对于不典型的病例还较难做出正确诊断。

Abstract: | Objective To study the MRI features of primary central nervous system lymphoma(PCNSL).Methods A retrospective analysis was performed in 7 patients with PCNSL according to its MRI features.Results The single lesion was found in 4 cases and multiple ones in 3 cases.Among the 11 lesions,4 located in frontal lobe,2 in parietal lobe,temporal lobe,cerebellar hemisphere,and 1 in corpus callosum.MR images revealed that the tumors was hyper or slightly hypo-intense on T1 weighted images and hyper or slightly hyper-i... |
