摘　　要：目的:探讨肺部真菌感染的CT影像学特点,提高对该病的认识。方法:回顾性分析26例经病理、真菌培养、临床治疗随访证实的肺部真菌感染的CT表现。结果:26例病变均累及多个肺段、肺叶和/或两侧肺,而且多种病变形态共存,其中肺炎性浸润实变、结节型12例,炎性浸润实变、肿块型3例,炎性浸润实变、结节、肿块型5例,多发结节型11例,结节、肿块型5例;13例出现"晕征",3例有"空气半月征";12例合并空洞,5例曲菌球,7例有楔形实变影,4例胸腔积液。结论:肺部真菌感染CT表现为病变呈多灶性、多态性,真菌感染的"晕征"及楔形实变影是早期肺部真菌感染的较特征性CT表现。Objective: To evaluate the CT image findings of pulmonary mycotic infection and to improve the knowledge of the disease. Methods: The CT manifestations of pulmonary mycotic infection in 26 cases confirmed by pathology, mycetes cultivation, and follow up of clinical theraphy were analyzed retrospectively. Results: 26 cases of lesions involving multiple lobe and/or both sides of lungs. 12 cases showed pulmonary inflammatory infiltration consolidation and nodus type, 3 cases showed inflammatory infiltration consolidation and tumour type, 5 cases showed inflammatory infiltration consolidation, nodus, and tumour type, 11 cases showed multiple nodus type , 5 cases showed nodus and tumour type. Among the 26 cases,Halo sign were showed in 13 cases,air cresent in 3 cases, accompanying with cavities in 12 cases, pulmonary aspergilloma in 5 cases, wedge shape consolidation in 7 cases, pleural effusion in 4 cases. Conclusion: Pulmonary mycotic infection display as mulifocality and polymorphism in CT. Halo sign and wedge shape consolidation of mycotic infection are comparative distinctive CT manifestations of the pulmonary mycotic infection.
