摘　　要：目的探讨隐球菌肺炎的临床特点,提高对隐球菌肺炎的认识。方法报道1例误诊为继发性肺结核的隐球菌肺炎的诊治经过。结果患者男性,32岁,因反复咳嗽、咳痰3月,规范抗结核治疗1月,咳嗽、咳痰无改善入院。实验室检查:经皮肺穿刺活检病理提示真菌感染,支气管肺泡灌洗液培养见新型隐球菌生长,对两性霉素、氟康唑、伏立康唑敏感。予氟康唑抗真菌治疗2周后,患者病情明显好转。结论隐球菌肺炎的临床症状与影像学表现无特征性,确诊需依靠病原学检查及病理活检。Objective To discuss the features of pulmonary cryptococcosis, and improve the diagnosis and treatment.Methods A case of pulmonary cryptococcosis reported, misdiagnosed as secondary pulmonary tuberculosis.
