目的:探讨肺隐球菌病的CT表现,提高对其诊断的准确率。方法:回顾性分析17例经病理证实的肺隐球菌病术前胸部CT表现。结果:病变表现为单发或多发结节或肿块,单发7例,多发10例,单发或多发合并斑片状影7例,病灶中边缘光整3个,模糊或不规则28个,9个伴有晕圈征,6个伴有坏死或空洞,4个见支气管充气征。结论:肺隐球菌缺乏特征性,临床表现与CT不符,多个病灶有集中趋势,结节与斑片并存,边缘有晕圈征时应考虑到本病可能。
Objective: To investigate the CT manifestations of pulmonary cryptococcosis and improve the accuracy of its diagnosis. Methods: A retrospective analysis of 17 cases of pathologically confirmed pulmonary cryptococcosis preoperative chest CT findings. Results: The lesions showed single or multiple nodules or masses, with 7 cases being single, 10 cases being multiple, 7 cases with solitary or multiple combined patchy lesions, 3 lesions in the margin, 28 fuzzy or irregular, 9 with halo sign, 6 with necrosis or voids, and 4 with bronchial insufflation. Conclusion: The lack of characteristic pulmonary Cryptococcus, clinical manifestations and CT does not match, multiple lesions have a concentration trend, nodules and patches coexist, the edge of a halo sign should take into account the possibility of the disease.
