Accessory-lobed accessory cardiac bronchus: Presentation and treatment in a pediatric patient

Abstract

Accessory cardiac bronchus (ACB) is a supernumerary bronchus usually arising from right main or intermediate bronchus. We report the case of a 9-year-old male who presented a 6-month history characterized by two right pneumonia episodes followed by persistent productive cough, recurrent bloody sputum, and chest x-ray persistence of a segmental thickening of right inferior lobe. Bronchoscopy revealed no abnormalities. Computed tomography documented an accessory-lobed ACB originating from right lower brochus. Surgical removal of ACB and related parenchyma was approached thoracoscopically and converted to thoracotomy for evidence of a bronchial injury. Two-year follow-up showed no recurrent infections or respiratory symptoms.
