Figure 11.

Chondrosarcoma: a 57-year-old male presented with dysarthria, dysphonia, rightward deviation of tongue and visual changes over the last three days. T2-weighted images show increased signal intensity within the left jugular foramen (green arrows), with an associated increased signal in the left sigmoid and anterior transverse sinuses. The lesion shows restricted diffusion on DWI (orange arrows) with a low ADC value, suggestive malignant mass. PET-CT failed to show tracer uptake in the mass. DWI: diffusion-weighted imaging; ADC: apparent diffusion coefficient; PET-CT: positron emission tomography computed tomography.
