Chronic eosinophilic pneumonia: clinical perspectives

Figures & data

Figure 1 Chest X ray of a patient with CEP demonstrating peripheral opacities.

Abbreviation: CEP, chronic eosinophilic pneumonia.

Figure 2 CT coronal view of a patient with CEP demonstrating peripheral consolidation, with alveolar opacities asymmetrically more in the right upper lobe.

Abbreviation: CEP, chronic eosinophilic pneumonia.

Figure 3 CT axial view in the same patient demonstrating the right-sided pleural based consolidation.

Figure 4 Histopathology features of chronic eosinophilic pneumonia.

Notes: Alveolar spaces are filled with fibrinous exudate and numerous eosinophils (arrow). Eosinophils and macrophages infiltrate the interstitium (arrow head). H&E stain, ×200.

Table 1 CEP diagnostic criteria

1	Ongoing respiratory symptoms, usually >2 weeks duration
2	Eosinophila  Serum – eosinophilia ≥1,000/mm^3 or  Alveolar – >40% of cell count differential on BAL
3	Pulmonary infiltrates, usually with a peripheral predominance
4	Exclusion of other known causes of eosinophilic lung disease

Abbreviations: BAL, bronchoalveolar lavage; CEP, chronic eosinophilic pneumonia.
