Voice Change Due to Paratracheal Air Cysts

Abstract

Paratracheal air cysts are a rare entity in which cystic formation occurs adjacent to the trachea. Most patients with paratracheal air cysts are asymptomatic, and the cysts are detected incidentally on chest radiograph or computed tomography (CT) scan. Most symptomatic patients complain of pulmonary symptoms or repeated r espiratory i nfection. R arely, t he a ir c ysts c an l ead t o paralysis o f the recurrent l aryngeal n erve a s a result of direct compression. We report a case of a 59-year-old male patient who presented with voice change, and the cause was identified as paratracheal air cysts on a chest CT scan. Surgical resection via video- assisted mediastinoscopy was performed, and the voice recovered immediately after the operation.
