Abstract

Bronchogenic cysts are rare congenital lesions, especially during neonatal period, arising from anomalous budding of the primitive tracheobronchial tube that can produce symptoms of respiratory compromise in infants and childern. We experienced a case of bronchogenic cyst in a 2-day-old male neonate, admitted in our hospital, who had the symptoms of persistent stridor and swallowing difficulty. Barium esophagogram and bronchogram showed tracheal and esophageal displacement, and ultrasonography and computed tomography of neck showed well defined thick-waHed cystic mass lesion. After surgical excision of the cyst, the symptoms of persistent stridor and swallowing difficulty were solved. The cyst wall was lined by respiratory epithelium with areas of squamous metaplasia, consistent with a bronchogenic cyst.
