Chronic Eosinophilic Pneumonia Affects the Alveoli and Alveolar Septal Interstitium 
Chronic eosinophilia is characterised by alveolar filling with eosinophils and inflammatory exudates(a) and interalveolar interstitial thickening, (overlaid in red in b). The infiltrates are classically peripherally positioned, usually upper lobes, more commonly bilateral but can be unilateral, and manifest as consolidation and or ground glass opacities.  The CT shows bilateral peripheral consolidations in the upper lobes
