Epidermoid cyst in temple area with skull perforation

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 neurologi-cal symptoms and skull perforation. Herein, we report the case of a 34-year-old woman who un-derwent successful treatment of an epidermoid cyst in the temporal region accompanied by neu-rological symptoms. Accurate radiological evaluation and complete removal of the tumor and cap-sule play a vital role in ensuring favorable long-term outcomes. Computed tomography and mag-netic 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 neuro-surgeon is required for cases involving intracranial expansion and dural invasion.
