Lateral intraventricular epidermoid cyst: A case report

Background: Epidermoid cysts originate from ectopic embryonic epithelial cells and are a very common type of benign intracranial tumor. Epidermoid tumors located in the lateral ventricle are exceedingly rare. Case description: We present a rare case of a 55-year-old man complaining of a recurrent headache over a 2 year-period. A non-contrast CT scan and MRI of the head revealed a large mass within the right lateral ventricle. Gross total resection of the lesion was retained but unfortunately the patient refused surgery. The prognosis for patients who undergo surgery is excellent and depends on the quality of tumor removal.
