Radiologic appearance of a bronchial granular cell tumor with secondary obstructive changes

Bronchial granular cell tumor is a rare neoplasm. This report describes a 16-year-old female with this tumor in the right upper lobe. An ill-defined mass with peripheral infiltration was recognized on a chest radiograph. Thoracic computed tomography showed an intrabronchial mass lesion at the proximal portion of the bronchial bifurcation of the right B1 segment. The tumor completely occluded the bronchial lumen and thus caused obstructive changes of the lung distal to the tumor.
