目的：探讨新型隐球菌脑膜脑炎(CM)的MR特征以提高对本病的认识。方法分析15例CM患者的头部MR特征。所有患者均经腰穿脑脊液墨汁染色或病理确诊。15例患者共进行26次MR检查，6例行增强MR检查。结果新型隐球菌脑膜脑炎的MR主要表现皮质髓质交界区、半卵2中心以及双侧基底节区点状、片状、泡沫样T1WI低信号、T2WI高信号，FLAIR高信号病灶；增强MR常常表现为软脑膜的异常强化，还可表现为局部脑皮质肿胀、囊性病灶、脑积水、孤立性肉芽肿样病灶等。结论新型隐球菌脑膜脑炎的MR表现多种多样，缺乏特异性，认识其头部M砸特征对其诊断有重要价值。

Objective To investigate MR imaging features of cryptococcus meningoencephalitis (CM). Methods The MR imagings of 15 patients with CM were analyzed. All cases were confirmed by India-ink capsule staining of CSF or pathological examination. All the 15 patients received 26 times MR scans, 6 cases were performed with contrast enhanced MR scan. Results On MR imaging, the common manifestation were spotty or patchy and foaming-like lesions with low signal on T1-weighted, high signal on T2-weighted and FLAIR which located at corticomedullary junctions, semiovale center and bilateral basal ganglions. Linear-like leptomeningeal enhancement was found after contrast. Other findings included focal brain swelling, cystic lesions, hydrocephalus and solitary granuloma. Conclusions CM has multiple manifestations on MR imaging without specificity. MR imaging has important value for the diagnosis of CM.
