1 Chondrosarcoma: T2W axial (A and B) and fast fluid-attenuated inversion recovery coronal images show a large T2 hyperintense left cavernous sinus mass, extending upwards from the left petroclivical synchondrosis. Chondrosarcoma: T2W axial (A and B) and fast fluid-attenuated inversion recovery coronal images show a large T2 hyperintense left cavernous sinus mass, extending upwards from the left petroclivical synchondrosis. The low T2 foci correspond to the stippled calcified chondroid matrix. The Eustachian tube is blocked with secondary inflammatory changes in the mastoid air cells. Note the atrophy of the masseter, temporalis and pterygoids, reflecting the left trigeminal nerve dysfunction. There was also left tongue denervation (not shown) due to involvement of the left hypoglossal canal/nerve. There is oedema in the left temporal lobe.
