chronic eosinophilic pneumonia has consolidation with peripheral predominance


  • predominance for upper and middle lobes 1

  • Bilateral in 50% of case on normal CT and up to 97% on HRCT
  • upper lobe predominant, lower lung involvement is infrequent
  • pleural effusions are infrequent unlike AEP [^2]
  • Chest imaging findings are that of bilateral, usually peripheral or pleural-based, opacities and are often described as the "photographic negative" of pulmonary edema (Figure 1), and, although characteristic, this finding is usually seen in only about 25% of patients.
