目的：探讨隐球菌性脑膜炎临尿颅脑与CT的关系。方法：对已确诊的36例隐球菌性脑膜炎进行临床与颅脑CT扫描的比较分析。结果：本病颅脑CT的阴性率较高，达55．6％，CT表现与病程有一定的相关性，病程念长，阳性率意高；其CT改变无特异性，不同部位可呈多样化影像学改变，而不规则的低密度多见（31．6％）。结论：CT表现与临床症状不一致，CT的改变与疾病严重程度及预后无明显相关性。 Objective: To investigate the relationship between cryptococcal meningitis and urinary brain and CT. Methods: A comparative analysis of 36 cases of cryptococcal meningitis diagnosed by clinical and brain CT scan. Results: The negative rate of craniocerebral CT was 55.6%. There was a certain correlation between CT manifestations and the course of the disease. The duration of the disease was longer and the positive rate was higher. The CT changes were nonspecific and different parts could be varied Imaging changes, while irregular low-density more common (31.6%). Conclusion: CT findings and clinical symptoms are not consistent, CT changes and disease severity and prognosis no significant correlation.
