摘要

AIM:To investigate the chest radiographic and high resolution computed tomography(HRCT)chest manifestations in glucocorticoid-naive allergic bronchopulmonary aspergillosis(ABPA)patients.METHODS:This is a prospective observational study and includes 60 consecutive glucocorticoid-naive patients with ABPA who underwent chest radiography and HRCT of the chest(1.25 mm every 10 mm)in the routine diagnostic workup for ABPA.RESULTS:Chest radiographs were normal in 50%of cases.Of the remainder,most patients demonstrated permanent findings in the form of parallel line and ring shadows suggesting bronchiectasis.Consolidation was detected in 17 cases but in the majority,the corresponding HRCT chest scan showed mucus-filled bronchiectatic cavities.Chest HRCT was normal in 22 patients,while central bronchiectasis(CB)was demonstrated in the remaining 38 patients.Bronchiectasis extended to the periphery in 33%-43%depending on the criteria used for defining CB.The other findings observed on HRCT were mucoid impaction,centrilobular nodules and high-attenuation mucus in decreasing order of frequency.CONCLUSION:Patients with ABPA can present with normal HRCT chest scans.Central bronchiectasis cannot be considered a characteristic feature of ABPA as peripheral bronchiectasis is commonly observed.Consolidation is an uncommon finding in ABPA.
