A case report of segmental bronchial atresia: radiologic evaluation including computed tomography and magnetic resonance imaging.

Bronchial atresia is a rare anomaly that characteristically presents with a pulmonary nodule and hyperinflation of the lung distal to the nodule. To make this diagnosis definitively, invasive studies have been required. Now with the combined use of computed tomography and magnetic resonance imaging, a diagnosis can be made without resorting to invasive techniques. This article describes a case of bronchial atresia illustrating the noninvasive approach.
