Central neurocytoma, abbreviated CNC, is a rare intraventricular brain tumour that is typically attached to the septum pellucidum.^[1]

Incidence

CNC represent 0.25-0.5% of brain tumours.^[2]

Pathology

CNCs are characterized by perivascular pseudorosettes, circular/flower-like arrangements of cells with a small blood vessel at the centre, and polygonal small cells with a clear perinuclear halo. The main histomorphologic differential diagnosis is oligodendroglioma.

Treatment

The mainstay of treatment is surgical excision.^[3]

History

It was first described in 1982.^[2]

We retrospectively evaluated 12 patients with histologically verified central neurocytoma (CN) to identify the MRI characteristics associated with this tumour. All tumours had heterogeneous signal intensity in their solid components and seven had a "soap bubble" or spongy appearance. Spicules were i
