title: Extraventricular neurocytoma--report of a case.
abstract: Neurocytomas are typically located within the supratentorial ventricular system. Extraventricular neurocytoma is a rare brain tumour that poses diagnostic difficulty. We report a case of cerebral extraventricular neurocytoma. A 44-year-old man presented with a 6-month history of tonic-clonic seizures. Magnetic resonance imaging demonstrated a left frontoparietal mass lesion. The patient underwent surgical therapy, and a radical excision was performed. The histological appearance and immuno-histochemical findings of the tumour are consistent with an extraventricular neurocytoma with anaplastic features. An excellent prognosis can be expected if a gross total resection is achieved. Postoperatively, radiotherapy and chemotherapy may be used as adjuvant therapies.
