Branchial cysts in the parapharyngeal space are rare. Until now, only 23 such cases have been reported in the literature. In this article, we report a new case in a 65-year-old man. Information gained from the clinical examination, fiberoscopy, and computed tomography revealed that the cyst was obstructing the oropharynx and filling the parapharyngeal and retropharyngeal spaces on the right. The mass was excised via a transcervical approach without any complications. We also review the literature on this condition.
