Epileptogenic Temporal lobe Intrinsic Epidermoid Tumor: A Rare Case Report and Review of the Literature

Abstract

Intracerebral epidermoid cysts are uncommon, accounting for only around 1.5 percent of intracranial tumors. Among these, Temporal lobe intracerebral epidermoid tumors are exceedingly rare. The great majority of these slow-growing tumors are asymptomatic, whereas few exhibit overt symptomatologies. We report a case of epidermoid tumors in a unique location, presented as a secondary complex partial seizure. A forty-year-old female presented with multiple episodes of convulsions followed by loss of consciousness for nine months, increasing in frequency over the last two months. MRI of the brain without contrast showed a well-circumscribed right temporal lobe mass, appearing hypointense on the T1 and hyperintense on the T2 sequence. In addition to our experience and review of existing literature demonstrate gross total resection of these lesions confers control of localization-related epilepsy.
