Abstract:Objective To evaluate the MSCT appearance of allergic bronchopulmonary aspergillosis (ABPA). Methods The MSCT and clinical data of 25 patients with clinically confirmed ABPA in our hospital were analyzed retrospectively. Results All patients showed central bronchiectasis; mucus plugs were found in 23 cases presenting with toothpaste, finger and dendritic distribution. Bilateral upper lobes involvement (n=19),right middle lobe involvement (n=7),left lower lobe involvement (n=4) were classified. The CT attenuation of mucous plugs in 15 cases was greater than the density of the same level of thoracic muscle,in which 4 cases were greater than 100 HU. Other features included tree-in-bud sign and centrilobular nodules in 22 ca-ses,accompanying with pneumonia in all cases,and pulmonary consolidation or atelectasis in 17 cases. Conclusion The char-acteristic manifestions of ABPA on CT are central bronchiectasis of upper lobes, mucoid plug impaction (usually high attenua-tion),tree-in-bud sign and centrilobular nodule,which can facilitate for the diagnosis of ABPA.
