title: Synovial sarcoma of the infratemporal fossa with intracranial extension.
abstract: Synovial sarcomas (SS) account for 7-8% of soft-tissue cancers and 3-5% of all cases with head and neck involvement. Synovial sarcoma of the infratemporal fossa is very rare In this article, we report the fourth case of SS of infratemporal fossa and the first case with intracranial extension via the foramen ovale. A 31-year-old man admitted with a one-year history of intense pain in his right jaw. On physical examination, there was only hyperesthesia over the right mandible side. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a mass in the infratemporal fossa and intracranial extension from the foramen ovale. The mass was surgically removed en bloc. Postoperative pathological examination reported the mass as a biphasic-type synovial sarcoma. The patient who received postoperative chemoradiotherapy had no recurrent disease for one year. The patient is still being followed in our clinic.
