CT

Computed tomography can help characterize the distribution of opacities and guide selection of an area of involvement for bronchoalveolar lavage. [19].

Characteristic CT findings of CEP include: 43 61 63 64 65 61

• 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 [61].
