摘　　要：目的:对免疫功能正常患者的原发性脑内淋巴瘤影像进行分析。方法:对10例免疫功能正常、经病理证实的原发性脑内淋巴瘤的CT、MR所见进行回顾性分析。结果:肿瘤以单发为主,大多发生在幕上,CT扫描多表现为等或稍高密度肿块;MRT1加权像呈低信号,T2加权像呈高信号;CT和MR增强扫描病灶多呈明显均匀强化。结论:原发性脑内淋巴瘤少见,影像检查对诊断有重要帮助。Objective:To analyze the imaging findings of primary brain lymphoma in immunologically normal patients.Methods:The clinical manifestations and imaging findings of 10 patients with pathologically proved primary brain lymphoma were reviewed.Results:Primary brain lymphoma mainly occurred as solitary lesion and mostly located at supratentorial region.Lesions presented as an isodense to hyperdense mass on CT scan,hypointense on T_1WI and hyperintense on T_2WI.Most lesions showed homogenous enhancement on CT and MR.Conclusion:Primary brain lymphoma is a rare tumor.Imaging examination plays an important role in diagnosis.
