原发性肺隐球菌病肿块结节型的CT表现

目的分析原发性肺隐球菌病肿块、结节型的CT表现,并与肺部恶性肿瘤鉴别,以提高对本病的认识。方法回顾性分析2例经病理证实的肿块、结节型肺隐球菌病患者的CT表现,结合文献总结原发性肺隐球菌病的CT表现。结果 2例患者中均无基础疾病,1例临床表现为畏冷、发热伴咽痛、咳嗽,1例无明显症状。CT表现为单发结节型1例,结节、肿块混合型1例。经手术切除病理证实1例,肺穿刺活检证实1例。结论原发性肺隐球菌病的CT表现缺乏特异性,尤其是肿块、结节型,容易误诊为肺部恶性肿瘤,确诊主要依赖病理学检查。

The CT findings of mass and(or) nodule of primary pulmonary cryptococcosis

Objective To analyze the CT findings of mass and （or）nodule of primary pulmonary cryptococcosis （PPC）,and differentiation from malignant tumor of pulmonary in order to improve the identification of this disease. Methods The CT manifestations of 2 cases with mass and（or） nodule of PPC proved by pathology were retrospectively analyzed,and the literature was reviewed to study imaging findings of PPC. Results 2 cases of PPC were juvenscence without fundamental disease. The patient of case 1 had mild cough and fever,the other was entirely symptom free. The CT manifestations included solitary nodule in 1 case,multiple pulmonary masses or nodules in 1 case.1 case was confirmed by operation and pathology,the other by lung biopsy. Conclusion The CT findings of PPC are not specific, especially mass, nodules, easily misdiagnosed as lung malignant tumor. The confirmed diagnosis of PPC mainly depended on the pathological examination.
