Imaging findings in the pulmonary aspergilloses can answer important clinical questions. Steroid-responsive chronic asthma due to allergic bronchopulmonary aspergillosis can be differentiated from simple asthma by computed tomography (CT) evidence of extensive and severe central bronchiectasis, mucoid impaction, or small airways lesions. The simple aspergilloma can be differentiated from the complex aspergilloma by the absence of: constitutional symptoms, para-cystic lung opacities, cyst expansion, or progressive pleural thickening. The CT halo sign is a transient finding that can provide a probable diagnosis of early invasive pulmonary aspergillosis in patients who are at extraordinarily high risk of the infection. Patients with a halo sign at baseline are more likely to have a satisfactory treatment response than those without this indicator.
肺曲霉病的影像学表现能够回答重要的临床问题。变应性支气管肺曲霉病所致的激素反应性慢性哮喘可通过计算机断层扫描（CT）显示的广泛且严重的中央型支气管扩张、黏液嵌塞或小气道病变与单纯哮喘相鉴别。单纯曲菌球可通过不存在以下情况与复杂曲菌球相鉴别：全身症状、囊肿旁肺实质混浊、囊肿扩大或进行性胸膜增厚。CT晕征是一种短暂性表现，可对感染风险极高的患者早期侵袭性肺曲霉病作出可能的诊断。基线时出现晕征的患者比无此征象的患者更有可能获得满意的治疗反应。
