A Case of Tracheal Bronchus / 소아알레르기및호흡기학회지

ABSTRACT

Tracheal bronchus is an aberrant bronchus that arises most often from right tracheal wall above the carina. It is a rare congenital anomaly, which is usually asymptomatic but occasionally associated with recurrent pneumonia, chronic bronchitis and bronchiectasis. Anomalies found in association with tracheal bronchi include respiratory(tracheal hypoplasia, tracheal stenosis, cystic lung lesion), gastrointestinal and musculoskeletal systems. Tracheal bronchus has been diagnosed by conventional tomography, bronchography and bronchoscopy in the past. Technical advances have greatly enhanced the utility of this diagnostic modality. So chest CT, even three-dimensional reconstruction, is of particular importance in the evaluation of mediastinal, pleural and lung parenchymal lesions. We experienced a case of duodenal atresia and tracheal bronchus in 6-month-old child who suffered from recurrent pneumonia and dyspnea. So we report with a brief review and its related literatures.
