摘要
目的探讨孤立性结节/肿块型肺隐球菌病的CT特征,提高对该病的认识。方法回顾性分析经临床证实的18例孤立性结节或肿块型肺部隐球菌病的CT表现。结果本组18例结节/肿块分布于下叶、胸膜下各有12例,胸膜反应多见(11/12);14例直径小于3cm,13例边缘清楚,9例伴空洞形成,其中7例为AIDS患者;分叶征(3/18)、毛刺征(4/18)、晕征(2/18)均少见;10例行CT增强的病灶中有7例呈现中度均匀强化。结论孤立性结节/肿块型肺隐球菌病的CT表现具有一定特征性,需在鉴别诊断中加以重视。
Objective To investigate CT features of pulmonary cryptococcosis （PC） in solitary nodular or mass-like pat- tern, in order to improve the identification of this disease. Methods CT appearance of 18 cases with clinically proved PC in solitary nodular or mass-like pattern was retrospectively reviewed. Results 12 of 18 cases of nodule/masse were located in lower lobe and subpleural regions respectively, of which 11 were found pleural reaction. Lesions had diameter measured less than 3 cm in 14 cases and had clear margin in 13 cases. The presence of cavitations within nodules/masses was found in 9 cases and 7 of them were found in AIDS patients. Lobulation （3/18）, speculation （4/18） and halo sign （2/18） were less common CT appearance. 7 of 10 cases underwent CT enhancement scan and appeared as uniform density and moderate enhancement. Conclusion PC in solitary nodular or mass-like pattern has certain characteristic presentation on CT ima- ging, and should be considered in the differential diagnosis of SPN.
