目的 探讨原发浸润性肺真菌感染的CT表现特点.方法 选取2007年12月-2011年6月于医院采用CT进行诊断检查的24例原发浸润性肺真菌感染患者为研究对象,将其不同感染分类的CT表现特点进行统计分析.结果 24例原发浸润性肺真菌感染患者感染病原菌分别为曲霉菌属占41.7％、白色假丝酵母菌占25.0％、放线菌占20.8％等,病灶表型比例由高到低为曲菌球型占41.7％、弥漫型占29.2％、实变型占20.8％及结节型占8.3％,各型CT表现各有特点.结论 原发浸润性肺真菌感染的CT表现有其特有的特点,在疾病诊断中有一定的辅助价值.

Analysis of CT manifestations in 24 patients with primary invasive pulmonary fungal infections

OBJECTIVE To investigate the CT manifestations of primary invasive pulmonary fungal infections.METHODS A total of 24 patients with primary invasive pulmonary fungal infections who received diagnosis with CT examination in our hospital from Dec 2007 to June 2011 were recruited.Statistical analysis was performed for CT manifestations of various types of infections.RESULTS The pathogens causing primary invasive pulmonary fungal infections in 24 patients were Aspergillus(41.7%),Candida albicans(25.0%),Actinomycetes(20.8%),and so on.The proportion of lesion phenotype from high to low were aspergilloma type(41.7%),diffuse type(29.2%),consolidation-type node(20.8%) and nodule type(8.3%).CT manifestations of each type had special features.CONCLUSION The CT manifestations of primary invasive pulmonary fungal infection has its unique characteristics,which may benefit to the disease diagnosis.
