Central neurocytoma--a rare benign intraventricular tumor.
Two cases of Central neurocytoma arising in the lateral ventricles are presented. Both patients had well-circumscribed masses in the right lateral ventricle causing hydrocephalus. The tumors were composed of small round cells forming Homer Wright rosettes against a fine fibrillary background. In one patient surgical removal was complete and no recurrence has been noted approximately one year later. These tumors appear to be benign and complete surgical excision should be curative.
