Definition
Central neurocytoma is a WHO grade II intraventricular neuroepithelial tumor of the young adult.
Clinical features
- Young adult
- Symptoms of increased intracranial pressure
- Seizure
- Rarely: intraventricular hemorrhage
CT
Intraventricular lesion, often located in the lateral ventricles near the foramina of Monro, which may extend into the third ventricle and be bilateral.
Hyperdense relative to white matter
Punctate calcifications (50%)
Moderate contrast enhancement
Obstructive hydrocephalus
MRI
Intraventricular lesion, often located near the foramina of Monro, which may extend into the third ventricle and be bilateral, with obstructive hydrocephalus
Isointense to cortex on T1 and heterogeneous
Moderate contrast enhancement after injection
Possible microcystic areas hyperintense on T2
T2*/SWI hypointensities of calcifications
Intralesional hemorrhage in cases of large lesions
Decreased ADC coefficient of the solid component
Spectroscopy: marked choline peak. Glycine peak at 3.55 ppm
Management
Complete surgical resection: favorable prognosis
Differential diagnosis
