Abstract:
Objective To analyze the CT manifestations of allergic bronchial pulmonary aspergillosis (ABPA),and to strengthen the understanding of the CT signs of the disease and improve the diagnostic level.Methods The CT data of 8 patients with ABPA diagnosed by fiberoptic bronchoscopy and pulmonary puncture pathology were analyzed retrospectively.All patients underwent chest CT scan, of which 5 patients underwent contrast enhanced scan.Results ① Location:the lesions happened in bilateral upper lobes and dorsal segments of lower lobes in 5 cases,bilateral diffused distribution in 1 case,right middle lobe in 2 cases.②Shape:1 case showed patchy increased density with blurred boundary;6 cases showed varied multiple bronchial cast mainly distributed in the internal 2/3 lung field(including the tree fork sign,glove sign and toothpaste levy)and combined with beaded,ground glass opacity (GGO),mixed density leions.③Cavity:cavity in 5 cases were round with smooth thin wall,of which 1 case showed movable aspergilloma.④Enhancement performance:there were heterogeneous enhancement of the bronchial wall in 4 cases.Conclusion CT features of ABPA showed no specificity,with polymorphism,variability,migration.Clinical diagnosis should be made by combining peripheral blood eosinophil ratio,eosinophil count,total serum IgE,aspergillus fumigatus antigen intradermal test,aspergillus allergic skin test and other laboratory tests with fiberoptic bronchoscopy,lung biopsy.
