An unexpected finding of a bronchogenic cyst presenting as a thyroid mass

Herein we present a case of a bronchogenic cyst masquerading as a thyroid mass. Bronchogenic cysts are rare congenital malformations that result from an abnormal development of the ventral foregut during organogenesis. They are commonly asymptomatic lesions rarely found in the neck. In our case, a young male presented with complaints of neck discomfort over a long period presumed to be secondary to a thyroid mass based on imaging studies. Fine needle aspiration was inconclusive. Post-operative pathological sectioning revealed evidence of a bronchogenic cyst. These lesions have a low incidence of malignancy, and complete surgical excision has been recommended.
