Abstract

Epidermoid cysts are benign tumors that account for approximately 1% of intracranial tumors. In very rare cases, temporally located extradural intradiploic epidermoid cysts can cause neurological symptoms and skull perforation. Herein, we report the case of a 34-year-old woman who underwent successful treatment of an epidermoid cyst in the temporal region accompanied by neurological symptoms. Accurate radiological evaluation and complete removal of the tumor and capsule play a vital role in ensuring favorable long-term outcomes. Computed tomography and magnetic resonance imaging scans can provide an accurate assessment of the extent of intracranial expansion and invasion of the cerebral parenchyma, as well as enabling the precise localization and characterization of the bone defect and mass. In addition, collaborative surgery with a neurosurgeon is required for cases involving intracranial expansion and dural invasion.
