目的探讨血液病患者侵袭性肺曲霉菌病(IPA)的CT特征。方法经临床及痰培养证实的IPA 9例,均行CT检查,5例行2次以上CT复查。分析IPA的CT表现。结果病变以双上肺及下叶背段多见,多分布于肺野外带及胸膜下。双肺多发结节5例,单发结节2例,胸膜下楔形实变2例,病变周围均见磨玻璃密度,其中1例伴双肺多发有晕征的结节。9例中,结节周围晕征6例,出现空气新月征或空洞6例。4例双肺野可见散在片状磨玻璃密度及斑片状渗出影。5例胸膜下病变引起邻近胸膜轻度增厚。结论血液病患者IPA发病率较高,该病具有一定的CT特征。
Objective To investigate CT features of invasive pulmonary aspergillosis (IPA) in patients with hematological diseases. Methods Nine cases of IPA confirmed by clinical and sputum culture were examined by CT and 5 cases were examined by CT twice or more. Analysis of IPA CT performance. Results The lesions were more common in the upper and lower lobes of the lungs and were mostly distributed in the lung and subpleural. Pulmonary multiple nodules in 5 cases, solitary nodules in 2 cases, subpleural wedge-shaped consolidation in 2 cases, the lesions around the ground glass density, including 1 case with multiple pulmonary lung signs of halo nodules. Among the 9 cases, 6 cases of halo around the nodules showed air crescent or empty holes in 6 cases. 4 cases of lung field can be seen scattered patch mill glass density and patchy exudation. 5 cases of subpleural lesions caused by mild pleural thickening. Conclusion The incidence of IPA is high in patients with hematological diseases and has certain CT features.
