摘　　要：目的探讨艾滋病合并新型隐球菌脑膜脑炎的MRI表现。材料与方法回顾性分析14例AIDS合并新型隐球菌脑膜脑炎患者的MRI资料。结果 14例患者的MRI中有13例呈阳性表现(92.86%),其中胶状假囊及以胶状假囊引起的血管周围间隙扩大6例(42.29%);脑膜炎4例(28.57%);结节性肉芽肿(即隐球菌瘤)3例(21.43%);局灶性脑水肿2例(14.29%);脑积水1例(7.14%);脑萎缩1例(7.14%)。结论艾滋病合并新型隐球菌脑炎的MRI表现呈多样化,主要表现为脑膜炎型、脑膜脑炎型及脑炎型,其中胶状假囊和胶状假囊引起的血管周围间隙扩大是其特征性表现。Objectives： To characterize the cranial magnetic resonance imaging findings of cryptococeus meningoencephalitis in AIDS （Acquired immunodeficiency syndrome） patients. Materials and Methods： The magnetic resonance imaging features of intracranical eryptocoecus meningoencephalitis in 14 patients with AIDS were retrospectively analyzed. Results： Intracranial lesions were found in 13 cases of the 14 patients （92.86%） with MRI head scan. Gelatinous pseudoeysts and dilated V-R （Virchow-Robin） spaces were seen in 6 cases （42.29%）, cephalomeningitis were seen in 4 cases （28.57%）, granuloma （crytococcomas） were seen in 3 cases （21.43%）, focal encephaledema were seen in 2 cases （14.29%）, hydrocephalus were seen in 1 case （7.14%）, encephalatrophy were seen in 1 case （7.14%）. Conelusions： MRI showed multiplex characteristic of cryptococcus meningoencephalitis in AIDS patients. Meningitis, meningoencephalitis and encephalitis were the principal types of MRI findings, and gelatinous pseudocysts and dilated V-R （Virchow-Robin） spaces may be considered specific for the diagnosis of cryptococcus meningoencephalitis.
