Summary:

Description	Radiopaedia case ID: 5421 Image ID: 21386 Image stack position: 1/7 Plane projection: Axial Aux modality: T2 Study findings: Selected MRI images confirm the presence of an extra-axial lesion arising from just lateral to the clivus and cavernous sinus. It is heterogeneous in signal with the more medial component demonstrated high T2 signal and variegated contrast enhancement, without restricted diffusion. Features are consistent with a chondrosarcoma (histologically proven). The off-midline location and ring-like calcification make a chordoma much less likely. Modality: MRI System: Central Nervous System Findings: An extra-axial lesion arising from just lateral to the clivus and cavernous sinus is noted. It is of mixed density with regions of calcifications. The location and appearance are suggestive of a chondrosarcoma. The off-midline location and ring-like calcification make a chordoma much less likely. A meningioma or trigeminal schwannoma are less likely possibilities.
