Central neurocytoma of the fourth ventricle. Case history.
Central neurocytomas are low-grade tumours of neuronal origin, affecting mainly young patients and usually located in the lateral or third ventricle. We report a rare case of central neurocytoma at the fourth ventricle level. Magnetic resonance imaging showed a homogeneously enhancing mass lesion at the fourth ventricle. Gross-total surgical removal was achieved. The histological diagnosis was of central neurocytoma but the lesion showed a fairly elevated Ki-67 index (6%). Given this finding, close neuroimaging monitoring was performed and at the moment the patient is free of recurrence.
