Abstract

anatomic evaluation with CT scan showed the anterior, apico-posterior and posterior segments, and two lingular subsegments arising directly from the LUL bronchus ( fig. 2 ). The patient had no other congenital anomalies. Cough resolved with treatment of gastroesophageal reflux disease. Tracheobronchial anatomic variations arise from embryogenic anomalies of supernumerary lung buds or lung buds arising from atypical sites. Congenital lobar and segmental bronchial variations are more common than tracheal or main bronchial anomalies, and they are A 55-year old female was seen in clinic for 6 weeks of nonproductive cough. Significant medical history included recurrent esophageal adenocarcinoma despite esophagectomy, chemotherapy and radiotherapy. Chest CT revealed recurrent esophageal tumor at the gastric pull-through site. Flexible bronchoscopy was performed to evaluate for possible tracheoesophageal fistula, however, none was found. Interestingly, an incidental finding of a five-orifice left upper lobe (LUL) bronchus was seen ( fig. 1 ). Bronchoscopic exploration of the five LUL segments revealed patent bronchi without atresia.
