Suprasternal bronchogenic cyst in an 8-year-old girl

Abstract: In this case report, we present an 8-year-old girl who was referred to the ear-nose-throat department of the Antwerp University Hospital because of an asymptomatic midline neck mass. After resection, histopathological examination was characteristic of a bronchogenic cyst. Bronchogenic cysts are rare, congenital anomalies of the tracheobronchial tree caused by aberrant bud formation of the tracheobronchial tree during embryogenic development. They usually have an intrathoracic location, whereas cervical, cutaneous, and subcutaneous cysts are extremely rare. Initial symptoms are respiratory distress, coughing, and bronchopulmonary infections by compression of the tracheobronchial tree. Imaging studies are recommended to determine the mass's tissue characteristics as well as the engagement of surrounding anatomical structures, which is necessary for adequate preoperative planning. However, a definitive diagnosis may be obtained only after surgery through histopathological analysis
