Intracranial Epidermoid Cyst in a Middle Aged Female: A Rare Case Report

Intracranial epidermoid cysts are uncommon congenital lesions which account for about <1% of all intracranial tumors.They are the consequence of ectodermal materials being included during neural tube closure, and because of the mass effect on surrounding tissues, they usually manifest in middle life.The material they contain is derived from desquamated epithelial cells.Epidermoid cysts are primarily congenital; however, they might take years to manifest since they grow extremely slowly.We present a rare case of intracranial epidermoid cyst extending into the frontal bone in a 57 years old female.Bifrontal craniotomy with excision of cyst was performed safely without any neurologic deficit.Subsequent histopathological analysis identified the lesion as an epidermoid cyst.
