title: Unilateral bronchial occlusion in a patient with sarcoidosis and a bronchial anomaly.
abstract: A patient with anomalous bronchial branching presented with marked stenosis and obstruction of the right mainstem bronchus due to sarcoidosis. Bronchoscopic and radiographic studies showed the right mainstem bronchus to be extensively involved with granulomatous inflammation, producing concentric cylindrical narrowing. Complete recovery occurred after one year of corticosteroid therapy.
