- Protracted course
- More symptomatic
- Mild to moderate eosinophilia
- Elevated serum IgE in peripheral blood
- Good prognosis
- Patients respond to steroids
- Chest Xray
- Patchy non-segmental consolidation
- Involves mid and upper zones
- Opacities peripheral and parallel to chest wall – photographic negative of pulmonary edema
