摘要
目的探讨颅内原发中枢神经系统T细胞淋巴瘤(T-PCNSL)的影像学特点。方法回顾性分析2例经病理学证实的T-PCNSL的MRI及MRS及表现。结果T-PCNSL影像学特点如下:好发于深部脑组织,如额叶、胼胝体及基底节区。病灶MRI上T1呈等、低信号,T2呈等、稍低信号,边界清楚。增强呈均匀明显强化,特征性的表现包括"缺口征"。在1H-MRS上,T-PCNSL特征性的表现为存在高耸的乳酸和脂质峰,胆碱/肌酸(Cho/Cr)比值增加,以及N-乙酰天冬氨酸/肌酸(NAA/Cr)比值下降。结论 T-PCNSL的MRI具有一定的特征性表现。
Objective To investigate the imaging features of intracranial primary central nervous system T-cell lymphoma(T-PCNSL).Methods Retrospective analysis of 2 cases of pathologically confirmed T-PCNSL MRI and MRS and performance.Results T-PCNSL imaging features are as follows:occur in deep brain tissue,such as frontal lobe,corpus callosum and basal ganglia.MRI on the lesion was equal,low signal,T2 was equal,slightly lower signal,clear boundary.Enhance the performance was significantly enhanced,the characteristics of the performance,including"missing sign."On the 1H-MRS,T-PCNSL was characterized by the presence of high lactic acid and lipid peaks,increased choline/creatine(Cho/Cr)ratio,and N-acetylaspartic acid/creatine(NAA/Cr)ratio decreased.Conclusion The MRI of T-PCNSL has certain characteristic manifestation.
