[Cervical intramedullary neurofibroma].

Spinal neurofibromas make up a third of all tumours of the medulla. They are usually found to be intradural and extramedullary. Exceptionally they may be intramedullar. We describe the case of a patient with signs of slowly progressive compression of the medulla, who was operated on surgically for an intramedullary neurofibroma, after imaging studies. We review the previously published cases and analyse the different histogenic theories concerning this tumour.
