A Rare Case of a Compressive Intracranial Epidermoid Cyst in a 13-Year-Old Patient

Pediatric intracranial epidermoid tumors are rare, slow-growing benign cystic lesions primarily originating from the ectodermal cell line during human embryogenesis. Intraparenchymal epidermoid tumors typically present with headaches, seizures, and focal neurological deficits. Although CT of the brain may show non-specific findings, MRI studies are more reliable and have a high confidence value in diagnosing intracranial epidermoid cystic lesions. We report a young girl who presented with headaches and blurring of vision for a three-week duration. An MRI of her brain revealed a cystic lesion on the right side of the interpeduncular cistern and cerebellopontine angle (CPA) extending to the right optic chiasm, suggestive of an epidermoid tumor. The aim of reporting this case is to highlight the significance of having a high clinical suspicion of intracranial tumors based on the patient's clinical manifestations.
