Chronic eosinophilic pneumonia

  • 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
  • CT
    • Same findings as plain film, more apparent in CT
    • Differential: organizing pneumonia. Nodules are more common in organizing pneumonia rather than chronic eosinophilic pneumonia
