Abstract

Epidermal inclusion cysts constitute 1% of the intracranial tumors and 7% of the cerebellopontine angle ones.Cholesteatoma are benign lesions originated from the remains of ectodermic epithelial tissues remaining in the central nervous system when the neural tube closes between the third and fifth week of pregnancy. The case deals with a patient remitted from the Neurophthalmologic Consultation with migraine crisis and lesion on the III, IV, V cranial nerves, ophthalmologic branch, for two weeks. Image studies were carried out, showing a hypo dense tumor in the left silvian frontotemporal   region. It was taken as an arachnoid cyst. A pterional trans-silvian approach with neuroendoscopic support was applied, and the surgical team was surprised when they found a solid pearly tumor that was macroscopically identified as a silvian cholesteatoma. The cerebral tumor was totally resected.
