摘　　要：目的 :探讨CT和MRI对脑内原发淋巴瘤的诊断价值。方法 :对 12例经手术和病理证实的脑内淋巴瘤的CT和MRI影像学表现进行回顾性分析。结果 :单发 10例、多发 2例 ,CT表现多为等密度或稍高密度肿块。MRI表现T1WI呈等或稍低信号 ,T2 WI多为稍高信号 ,CT和MRI增强扫描多为均匀强化。结论 :脑内原发淋巴瘤少见 ,影像学表现与颅内其它肿瘤互相重叠 ,CT和MRI平扫和增强扫描的应用有助于脑内淋巴瘤的诊断和鉴别诊断。Objective:To investigate the role of CT and MRI in diagnosis of primary brain lymphoma.Methods:CT and MRI feature of 12 case with intracranial lymphoma,which were retrospectively analysed.Results:Lesions presented as an isodense to hyperdense on CT scan.The MRI appearances were as following:①T 1WI,the lesions were isointense or slightly hpopintense while isointense or slightly hyperintense on T 2WI;②inhomogeneous Gd DTPA enhacement presented in most of the tumors.Conclusion:Primary brain lymghoma is a rare tumor that imaging findings ovelap with those of other intracranial mass lesions.The application of plain and enhanccd CT and MRI scanning is helpful for the diagnosis and differential diagnosis of intracerebral lymghoma.
