An accessory cardiac bronchus (ACB) is a rare congenital anomaly of the trachobronchial tree. It rarely presents with symptoms, and is usually diagnosed incidentally by chest CT, bronchoscopy, or during surgery. We experienced a case of accessory cardiac bronchus found incidentally in the bronchus intermedius with lung cancer in the right lower lobe, and surgically removed.

Objectives : To evaluate the clinical significance of abnormal bronchi originating from the trachea or main bronchi. Methods : 21 patients (male:female ratio, 13:8; mean age, 58.2 years, range 34-77), who were diagnosed with major tracheobronchial anomalies by bronchoscopy from January 2001 to March 2005, were enrolled in this study. The anomalous bronchi consisted of 13 tracheal bronchi and 8 cardiac accessory bronchus. The clinical features, bronchoscopic findings, and outcomes were analyzed retrospectively. Results : Common symptoms, including hemoptysis, cough and dyspnea, resulted from the underlying lung disease regardless of the bronchial anomalies. In this series of 13 tracheal bronchi, 7 cases originated from the trachea within 1cm of the carina (carinal type) and 6 cases originated at a higher level(tracheal type). Most patients had favorable outcome with conservative treatment for the underlying lung disease. Conclusion : Most tracheobronchial anomalies are found incidentally in the process of diagnosing lung disease. The clinical outcome of patients with a bronchial anomaly depends on the underlying lung disease.
