Huge intraventricular epidermoid cyst: A case report.

Epidermoid cysts, originating from ectopic embryonic epithelial cells, are a common type of benign intracranial tumor. However, intraventricular epidermoid cysts are rare, with those occupying the lateral ventricles being exceptionally uncommon. This report details the case of a 59-year-old male presenting with recurrent headaches over an 8-month period, accompanied by behavioral changes, memory impairment, and seizures. Magnetic resonance imaging of the brain revealed a large intraventricular mass consistent with an epidermoid cyst. The patient underwent subtotal resection via a transfrontal transventricular approach, resulting in good postoperative recovery.
