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 interstitia l infiltrates on chest roentgenograms. Diagnosis was confirmed in each case by bronchoalveolar lavage and transbronchial lung biopsy in whic h the pathologic process was limited to the lung interstitium. High-re solution 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 resolve d spontaneously within two weeks. The HRCT-findings may reflect the pa thologic process in AEP and the ground-glass opacities likely indicate spontaneous resolution without corticosteroid therapy.
