肺部侵袭性曲菌病的CT表现

CT manifestations of invasive pulmonary aspergillosis

目的:总结侵袭性肺曲菌病的CT表现。方法:回顾分析了经病理确诊的侵袭性肺曲菌病21例,总结其CT表现并与病理对照。结果:21例患者中11例CT表现为不同程度的肺实变,8例患者表现为双肺散在或弥漫磨玻璃影,5例表现为肺内单发或多发结节或肿块,其中3例周围可见晕征,肺内单发或多发空洞3例。结论:肺实变、磨玻璃影、结节及肿块是侵袭性肺曲菌病较早期的表现,空气新月征及空洞影提示病变趋于好转。典型的晕征、空气新月征或空洞对诊断侵袭性肺曲菌病具有一定的特异性。

Objective： To summarize the CT manifestations of invasive pulmonary aspergillosis after solid orgon trampluntotion.Methods： The CT manifestations of 21 cases of invasive pulmonary aspergillosis which confirmed pathologically were retrospectively analyzed. The CT manifestations were concluded and they are compared pathologically. Results： Among these patients,11 cases revealed pulmonary consolidation. 8 cases showed ground glass opacity,5 cases displayed single or multiple nodule or masses（ 3 revealed peripheral halo sign） and 3 cases showed cavity. Conclusion： The early CT features of invasive pulmonary aspergillosis include air-space consolidation,ground glass opacity,nodule or masses. Air-crescent sign and cavitary lesion mean invasive pulmonary aspergillosis is getting better.The typical halo sign,air-crescent sign and cavitary lesion have some specificity in the diagnosis of invasive pulmonary aspergillosis.
