The posterior cranial fossa, the largest and deepest of the three cranial fossae, contains the most complex intracranial anatomy. That contains cerebellum, fourfh ventricle and 10 pairs of cranial nerves. The relationships of the fourth ventricle to the cerebellar surfaces and the fissures through which the ventricle is approached surgically are among the most complex in the brain. We reviewed and discussed about the microsurgical anatomy and surgical approaches to the fourth ventricle.

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.
