Faces of Chronic Eosinophilic Pneumonia

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

Upper Lobe Peripheral Infiltrates and Interlobular Septal Thickening in the RUL
CT scan in the coronal performed 6 months ago at the time of clinical presentation shows upper lobe predominant peripheral infiltrates with small left lower lobe peripheral infiltrate Subsequent diagnosis by BAL of chronic eosinophilic pneumonia (CEP)

Upper Lobe Peripheral Infiltrates with Air Bronchograms, and Interlobular Septal Thickening
CT scan in the coronal performed 6 months ago at the time of clinical presentation shows upper lobe predominant peripheral infiltrates more prominent in the left upper lobe. Subsequent diagnosis by BAL of chronic eosinophilic pneumonia (CEP) was made
