Acute eosinophilic pneumonia: radiographic and CT findings in six patients.
OBJECTIVE
Our objective was to assess the radiographic and CT findings of acute eosinophilic pneumonia.


CONCLUSIONS
Initial and follow-up chest radiographs, chest CT scans (n = 5) and clinical data in six patients with acute eosinophilic pneumonia were reviewed by two chest radiologists. The predominant initial radiographic finding was diffuse bilateral reticular densities (four [67%] of six patients). Areas of ground-glass opacity were observed on CT scans in all patients (5 of 5) and were bilateral, random, and patchy in distribution in four (80%) of five patients. Smooth septal thickening and pleural effusions were observed in four patients. The disease manifested as rapid onset of severe dyspnea and fever and rapid resolution with (n = 3) or without (n = 3) steroid therapy. Bilateral reticular densities on chest radiographs and, on CT scans, ground-glass opacity with smooth septal thickening and pleural effusion associated with acute fever and dyspnea may suggest the diagnosis of acute eosinophilic pneumonia.
