Acute Eosinophilic Pneumonia Evaluated with High-Resolution Computed Tomography.

We describe two cases of acute eosinophilic pneumonia (AEP) presenting with high fever and hypoxia of acute onset with bilateral interstitial infiltrates on chest roentgenograms. Diagnosis was confirmed in each case by bronchoalveolar lavage and transbronchial lung biopsy in which the pathologic process was limited to the lung interstitium. High-resolution computed tomography (HRCT) of the thorax at the height of the disease process revealed peripheral ground-glass opacities along the bronchovascular bundles. Symptoms and radiologic abnormalities resolved spontaneously within two weeks. The HRCT-findings may reflect the pathologic process in AEP and the ground-glass opacities likely indicate spontaneous resolution without corticosteroid therapy.(Internal Medicine 32: 891-894, 1993)
