摘要
目的:总结分析原发性脑内淋巴瘤的MRI特点,探讨MRI对该病的诊断价值,从而提高对该病的诊断水平。方法:回顾性分析16例经病理证实的原发性脑内淋巴瘤的资料,所有病例均进行MRI平扫和增强检查。结果:16例患者淋巴瘤单发11例,多发5例,单发者部位包括额叶、顶叶、颞叶、中脑及基底节区,共19个病灶。多数位于脑组织深部,MRI平扫表现为病灶边界清楚但不锐利,增强扫描后病灶显著均匀强化,呈团块状。结论:原发性脑内淋巴瘤的MRI表现有一定的特异性,仔细分析MRI影像特点,将其与临床资料综合分析,一般可获得较准确的术前诊断。
Objective：To explore the MR findings of primary lymphomas in the brain and to improve the accuracy of diagnosis.Methods：MR findings of 16 cases with primary lymphomas in the brain were retrospectively analyzed.Results：The lesions were single in 11 cases and multiple in 5 cases.The single lesions locted at the frontal lobe,apical lobe,temporal lobe,the middle brain and the basal ganglia.There were 19 lesions in 11 patients.Obvious homogeneousmass-like enhancement with small cystic degeneration and dispersive flocculent enhancement were showed.Conclusion：MRI findings of primary lymphomas in the brain have some characteristics,It is possible to make a correct preoperative diagnosis in most cases of primary lymphomas if doctors pay more attention to the analysis of the MRI.
