The roentgenographic manifestations of bronchocentric granulomatosis were reviewed in 15 patients. Nine patients had mass lesions. Four had alveolar infiltrates and 2 presented with reticulonodular infiltrates . Correlation of these radiographic patterns with the pathologic findings helps explain the varied morphologic appearance of this disease on the chest radiographs. Upper lobe involvement and unilateral disease were predominant. Seven of 15 patients (47%) presented with solitary mass lesions. Pleural reaction was occasionally noted. Hilar adenopathy and cavitation were infrequent. There was little correlation between radiographic pattern and clinical presentation.
