Chordoid meningioma

Abstract

This special type of meningeoma was described as characterized by nests and cords of cells with the morphology of meningothelial cells, in a myxoid stroma. No peritumoral lymphoplamacellular infiltrates was found in this case. Our case was a 52 year old man with severe pain in right VI and VII distribution that was operated upon 4 years ago and had the diagnosis of trigeminal neuroma of the posterior fossa. On neurological examination his right vision was well preserved but with restriction of all external orbital muscles on that side. MRI revealed a large mass occupying the right temporal and infratemporal fossa and invading the cavernous sinus. A cranio-orbitozygomatic approach was done with partial remove of the tumor mainly the part involving the cavernous sinus because of the intense bleeding. The tumoral bed was fill with fat and fascia lata was used to avoid CSF leak. The patient is well and is controlled every 6 months. Radiotherapy was avoided.
