Abstract:
Objective To investigate the initial CT characteristics and dynamic changing features of invasive pulmonary aspergillosis (IPA).Methods CT findings of 40 patients with IPA confirmed by histopathology or clinics were analyzed retrospectively,including the initial and follow-up CT features.Results Multiple lesions in the bilateral lung were found in the initial CT of all 40 patients.The coexistence of no less than two different CT features were showed in 27 patients(67.5 ％),and the same CT morphologic feature were showed in 13 patients (32.5 ％).The common features of the initial CT:nodules/masses (34,85.0 ％),halo sign (24,60.0％),patchy opacities (13,32.5 ％),cavities (9,22.5 ％) and wedge opacities adjacent to pleura (3,7.5 ％).The follow-up CT showed that cavities or air meniscus sign emerged in the nodules/masses after an effective treatment in 29 patients (72.5％) of all 40 cases.The lesion volume decreased subsequent to the collapse of the cavities or air meniscus,and then vanished.Conclusion Thoracic CT scanning play an important role in the diagnosis of IPA.Coexistence of the multiple lesions in number and morphology is the most common CT feature.The findings of follow-up CT is characteristic,and can be helpful in guiding the clinical treatment and evaluating therapeutic effect.
