year-old male patient presented with a headache. This axial FLAIR (fluid-attenuated inversion recovery) MR image shows a right ventricular mixed solid/cystic mass limited by the septum pellucidum and ventricular walls. The solid portions of the tumour showed heterogeneous enhancement on post-gadolinium sequences. Based on these imaging characteristics a provisional diagnosis of central neurocytoma was made. The tumour was resected the next day - histology and immunocytochemistry confirmed the diagnosis.
• Central neurocytoma - Ganzer Fall bei Radiopaedia
A neurocytoma is WHO grade II primary CNS neoplasm which is derived from neural cells.
There are two main types:
- intraventricular neurocytoma
- much more common
- it called a central neurocytoma when it located centrally within the lateral ventricles
- extra ventricular neurocytoma (EVN)
Both types tends to have similar biological behavior and have similar demographics .
