Congenital bronchial atresia with partial anomalous pulmonary venous return

A 35-year-old woman with a high fever had a cystic lesion of the right lung including fluid and air. She was diagnosed with an infected bronchial cyst caused by congenital bronchial atresia with partial anomalous pulmonary venous return. She underwent a right upper lobectomy successfully. Patients with congenital bronchial atresia often have recurrent pulmonary infections with various imaging findings. The aberrant vein may relate to interruption of the bronchus in a patient with partial anomalous pulmonary venous return. Although segmental resection is recommended for this benign disease, lobar resection may be unavoidable because of adhesions or destruction of adjacent segments.
