Stereotactic radiosurgery with Cyberknife: first case in the United Arab Emirates (a case report).

A 64-year-old gentleman was referred to the department of oncology with severe pain in the right ear radiating to the right side of the face. Imaging revealed a large extra-axial expansile lesion, surrounding and encasing the right cavernous sinus extending to the right middle cranial fossa. The patient consulted several neurosurgeons and was recommended stereotactic radiosurgery with Cyberknife as the best non-invasive modality. The proximity to the critical structures, such as the brainstem, made it challenging for any surgical approach. The patient completed stereotactic radiosurgery with Cyberknife and is doing well one month after treatment.
