Overview
Characteristic CT findings of CEP include ground-glass attenuation, consolidation, Nodules, septal thickening, Pleural effusions, and thickening of bronchovascular bundles.
CT
Computed tomography can help characterize the distribution of opacities and guide selection of an area of involvement for bronchoalveolar lavage.[1]
Characteristic CT findings of CEP include:[2][3]
- Ground-glass attenuation
- Consolidation
- Nodules
- Septal thickening
- Pleural effusions
- Thickening of bronchovascular bundles
- The lesions usually involve the peripheral regions of the middle or upper lung zones.
- The radiologic diagnosis of other causes of eosinophilic lung such as drug-induced pulmonary eosinophilia and hypereosinophilic syndrome is rarely possible.
- Common CT findings of ABPA consist of bronchiectasis, mucous plugging, bronchial wall thickening, atelectasis, consolidation, areas of ground-glass attenuation, and upper and central lung predominance.[4]
