An Adult Tracheocele with No Predisposing Factor

Abstract

Tracheoceles are rare, and usually, they have been described as incidental findings while evaluating patients for other problems. Our patient complained of a mass located in the right supraclavicular region that got larger on coughing and straining; otherwise, he was asymptomatic. His history did not reveal any predisposing factors. Computed tomography showed an air-filled 3x2.5x2 cm mass at the level of the T2-4 vertebrae. Surgical exploration showed an air-filled mass located between the common carotid artery and trachea, communicating with the tracheal lumen via a narrow tract attached to the posterior wall of the trachea. The mass was completely resected, and the defect in the posterior wall was repaired. A literature search revealed only one tracheocele case without any predisposing factors, and our case is a new one. It is different from other tracheocele reports considering the origin side, type, and level of the lesion.
