CT scans of 35 patients with intracranial cryptococcal infection were reviewed retrospectively. Studies were normal in 43% of the patients. Positive findings in others included diffuse atrophy in 34%, mass lesions (cryptococcoma) in 11%, hydrocephalus in 9%, and diffuse cerebral edema in 3%. Two unusual types of cryptococcoma were encountered, namely gelatinous pseudocysts and an intraventricular cryptococcal cyst. All findings were nonspecific for CNS cryptococcosis. The results suggest that CNS cryptococcosis should be considered in all patients at risk for the disease who have these abnormal CT findings, no matter what their initial clinical presentation. In addition, MR demonstration of gelatinous pseudocysts in one patient indicates that this technique may be helpful in locating cryptococcal mass lesions not visualized on CT.
对35例颅内隐球菌感染患者的CT扫描进行了回顾性研究。43%的患者检查结果正常。其他患者的阳性发现包括弥漫性萎缩（34%）、肿块病变（隐球菌瘤）（11%）、脑积水（9%）和弥漫性脑水肿（3%）。遇到了两种不寻常类型的隐球菌瘤，即胶冻样假性囊肿和脑室内隐球菌囊肿。所有这些发现对中枢神经系统隐球菌病都不具有特异性。结果表明，对于所有有患该病风险且有这些异常CT表现的患者，无论其最初的临床表现如何，都应考虑中枢神经系统隐球菌病。此外，一名患者的胶冻样假性囊肿的磁共振成像显示，该技术可能有助于定位CT上未显示的隐球菌肿块病变。
