Radiologic Findings: Chest PA shows diffuse confluent opacities with slight lower predominency. The main lesions are coalescent alveolar densities. Follow up chest PA a few days apart shows rapid aggravation of the diffuse disease with pneumomediastinum. CT scans show slight bronchovascular distorsions in addition to the almost same findings. One notes reticular densities, too. BAL fluid shows eosinophilia more than 30%. Therefore, initial clinical diagnosis was acute eosinophilic pneumonia.
The dyspnea and hypoxia was aggravated and she was referred to other hospital. Pneumomediastinum was developed. Open lung biopsy specimen revealed acute interstitial pneumonia (AIP). No pathologic organism was confirmed. Fibrosis of the lung was progressively aggravated and diffuse honeycoming lesions were developed.
