目的：研究脑原发性淋巴瘤的MRI影像学表现，提高对该病的正确诊断率。方法：回顾性分析20例经病理证实的原发性脑淋巴瘤患者的MRI影像学表现，所有病例均行MRI平扫及增强扫描。结果：20例患者中，单个病灶14例，多个病灶6例；幕上病灶17例，幕下病灶3例；共28个病灶，病理类型均为弥漫大B细胞型非霍奇金淋巴瘤。MRI平扫表现为T1WI为稍低信号，T2WI为稍高信号，少数为等信号；8例病灶内可见坏死囊性变，瘤周水肿相对较重，占位效应较重，中线结构移位较明显。MRI增强扫描，病灶大多呈明显均质强化。结论：原发性脑淋巴瘤MRI表现有一定的特征性，认真分析其影像学特点，结合临床可以给出倾向性诊断。
目的：研究腦原髮性淋巴瘤的MRI影像學錶現，提高對該病的正確診斷率。方法：迴顧性分析20例經病理證實的原髮性腦淋巴瘤患者的MRI影像學錶現，所有病例均行MRI平掃及增彊掃描。結果：20例患者中，單箇病竈14例，多箇病竈6例；幕上病竈17例，幕下病竈3例；共28箇病竈，病理類型均為瀰漫大B細胞型非霍奇金淋巴瘤。MRI平掃錶現為T1WI為稍低信號，T2WI為稍高信號，少數為等信號；8例病竈內可見壞死囊性變，瘤週水腫相對較重，佔位效應較重，中線結構移位較明顯。MRI增彊掃描，病竈大多呈明顯均質彊化。結論：原髮性腦淋巴瘤MRI錶現有一定的特徵性，認真分析其影像學特點，結閤臨床可以給齣傾嚮性診斷。

Objective:To analyze MRI features of Primary intracerebral Lymphoma and improve the accurate diagnostic rate of the disease. Method:MRI findings of 20 patients with pathologically proved Primary Brain Lymphoma were retrospectively analyzed. Result:There were 14 cases with single lesion and 6 cases with multiple lesions. The lesions of 17 cases distributed in supratentorium and of 3 cases in inferiortentorium. The total cases showed 28 lesions altogether. All cases were pathologically non-Hodgkin’s B cell type. On MRI,slightly hypointense on T1-weighted images and isointense or slightly hyperintense on T2-weighted images. There were severe peritumoral edema and space occupying effect of 8 lesions. Most lesions showed Obvious homogenous enhancement on MRI. Conclusion:MRI performance of primary brain lymphoma has certain characteristic,to analyze its imaging characteristics and combine with clinical orientation can form A diagnosis.
