Bronchial atresia: three-dimensional CT bronchography using volume rendering technique.
We report a case of asymptomatic bronchial atresia of the anterobasal and laterobasal segments of the right lower lobe. Because of the absence of typical bronchial mucocele on chest radiograph, it was difficult to base the diagnosis on chest radiography alone. Helical CT images demonstrated the characteristic appearance of bronchial atresia, and three-dimensional (3D) CT bronchography using the volume rendering technique helped us to comprehend the spatial relationship between the dilated bronchus distal to the atresia and the more proximal bronchus.
