title: Acute bilobar collapse secondary to endobronchial metastatic seminoma.
abstract: We report here a patient with tracheal and endobronchial metastatic seminoma who presented with acute respiratory failure with right upper and middle lobe collapse. Diagnosis of the etiology of the atelectasis was made by fiberoptic bronchoscopy. Radiation therapy caused a marked reversal of the atelectasis.
