Abstract

Schwannomas are the most common neurogenic tumours arising in the parapharyngeal space. Usually they arise from the vagus nerve but rarely have an extralaryngeal presentation arising from the superior laryngeal nerve. In the case reported here, cytology could not confirm the diagnosis and imaging could not identify the nerve of origin.

Keywords: Head and neck; Schwannoma; Superior laryngeal nerve.
