Epidermoid tumor rarely arises within the cavernous sinus and produce clinical symptoms. This 21-year old man presents with 6-year history of headache, diplopia, and ptosis. An evaluation revealed a mass located in the right cavernous sinus and he underwent gamma knife radiosurgery. But the symptoms did not improved, and there was slight increase in size of mass in follow-up evaluation. So, he underwent operation, the tumor was near-totally removed after surgery, and histologic finding revealed an epidermoid tumor. The patient was discharged with no newly developed neurologic deficits. In later three years follow-up, there was no evidence of recurrence. Magnetic resonance imaging, especially diffusion-weighted image, is a valuable tool in diagnosis of intracerebral epidermoid tumors. Radiotherapy is known to be ineffective for epidermoid tumors. Surgical removal should be attempted, but a less aggressive surgical strategy should be considered if there is strong adherence between the tumor capsule and the brain parenchyme particularly in eloquent areas. Regular long term follow-up is necessary for evaluation of recurrence.
