Imaging characteristics of a typical skull base chondrosarcoma in the right temporal skull base. CT angiography (A) highlights an internal chondroid calcification pattern (arrowhead) and anterior displacement of the paraclival carotid artery (arrow). T2-weighted axial MRI (B) shows a hyperintense right temporal extra-axial mass with hypointense internal calcification. T1-weighted axial postcontrast MRI (C) shows heterogeneous contrast enhancement.
CT: computed tomography; MRI: magnetic resonance imaging.
