艾滋病合并新型隐球菌脑膜脑炎的MRI表现

摘要

Objectives: To characterize the cranial magnetic resonance imaging ifndings of cryptococcus meningoencephalitis in AIDS (Acquired immunodeifciency syndrome) patients. Materials and Methods: The magnetic resonance imaging features of intracranical cryptococcus 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 pseudocysts 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%).Conclusions: MRI showed multiplex characteristic of cryptococcus meningoencephalitis in AIDS patients. Meningitis, meningoencephalitis and encephalitis were the principal types of MRI ifndings, and gelatinous pseudocysts and dilated V-R (Virchow-Robin) spaces may be considered speciifc for the diagnosis of cryptococcus meningoencephalitis.%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。
