Central Neurocytoma
- Central neurocytomas are typically seen in young patients (20–40 years of age), and constitute approximately 0.25–0.5% of all intracranial tumors.
- Clinical Presentation: Symptoms of increased intracranial pressure, or seizures
- Key Diagnostic Features: Most commonly, an inraventricular mass attached to septum pellucidum is seen. The typical cross-sectional imaging appearance of a central neurocytoma is a well-circumscribed, lobulated, intraventricular mass with numerous intratumoral cystlike areas. These cyst-like areas are noted in two-thirds of cases with imaging studies. Calcification, usually punctate in character, is present in half of the cases. Moderate enhancement is typical after the intravenous contrast administration on both CT and MR images.

- Rx: Surgical excision
