摘　　要：目的探讨免疫功能正常者肺曲霉菌病的影像学表现。方法收集9例经组织病理学确诊的免疫功能正常的肺曲霉菌病患者,回顾性分析其临床资料、X线片和CT表现。结果 9例患者均有胸片资料,其中8例有CT资料,且均接受增强CT检查。胸片示单发病灶1例,多发病灶8例,主要表现为多发结节影及大片状实变影,实变影及结节周围模糊,部分结节内可见空洞影。CT表现:肺部大片实变4例,其中3例可见"支气管气相征",实变并肺部小叶间隔增厚1例;肺部多发结节4例,结节周围可见"晕征";多数结节影沿支气管血管束分布,3例结节内见空洞,部分空洞内可见细线状分隔。增强后片状实变影及结节影均有强化,平扫CT值平均为(32.94±2.93)HU,增强后CT值平均为(64.13±6.31)HU。9例患者中3例合并胸腔积液。结论免疫功能正常者肺曲霉菌病影像学表现多种多样,但在部分患者可有一定的特殊表现。Objective To explore the imaging features of pulmonary aspergillosis in non-immunocompromised patients. Methods Nine non-immunocompromised patients with pulmonary aspergillosis confirmed by histopathology were collected, and their clinical data and imaging features were analyzed retrospectively. Results Nine patients underwent chest X-ray , 8 of them underwent plain and enhanced CT scan. Chest X-ray films showed 1 case with single lesion, 8 cases with multiple lesions, the borders of nodules or large consolidations were fuzzy, some nodules were found with cavities. CT perform- ances： Large consolidation was found in 4 cases, among them 3 with air bronehogram, 1 with interlobular septal thicken- ing. Multiple nodules were found in 4 cases, most with halo sign, manynodules distributed along bronchovascular bundles, and cavity could been seen in 3 cases, most with thin line separation. Enhancements were noticed in consolidations and nod- ules, the average CT ＇value of plain scan was （32.94±2.93）HU, of enhanced scan was （64.13 ± 6.31 ）HU. Three cases had pleural effusion. Conclusion The imaging findings of pulmonary aspergillosis are variety in non-immunocompromised patients, but some cases have special signs.
