摘　　要：目的：探讨 HIV 阴性患者肺隐球菌病（PC）的 CT 表现。方法回顾性分析26例经病理确诊的 PC 患者的 CT 资料,所有患者均行胸部 CT 平扫,其中8例行增强扫描。结果26例患者中在 CT 上表现为单发病灶11例,多发结节/肿块10例,混合型5例。病灶仅出现在左肺11例,右肺7例,双肺均出现病灶8例。19例可见毛刺,10例见空洞或空泡,8例见晕征。增强扫描1例病灶明显不均匀强化,2例表现为中度不均匀强化,3例轻度强化,2例病灶无强化。结论PC 在 CT 上表现多样,容易误诊为肺癌等其他病变。CT 引导下经皮肺穿刺活检是确诊的有效方法。Objective To analyze the CT findings of pulmonary cryptococcosis （PC）in patients without HIV infection.Methods CT data of 26 patients with PC proved by pathology were analyzed retrospectively.All cases underwent plain CT scan,8 of whom underwent contrast-enhanced CT scan.Results 26 patients （17 male and 9 female）,single lesion on CT was found in 11 cases,multiple nodules or masses in 10 cases,and mixed-type lesions in 5 cases.The lesion was located in left lung in 1 1 cases,in right lung in 7 cases and bilateral lungs in 8 cases.The lesions with burr sign were found in 1 9 cases,with cavities or vacuoles in 10 cases,and with halo sign in 8 cases.Enhanced CT showed marked heterogeneity in 1 case,moderate heterogeneity in 2 cases,slight enhancement in 3 cases and nonenhancement in 2 cases.Conclusion Lesions of PC with various CT findings are easy to be misdiagnosed as lung carcinoma or other lesions.CT-guided percutaneous lung biopsy is an effective method for diagnosis.
