  		Figure 4. (a) A 60-year-old man presenting with Type 3 (upward invasive type) spread. Axial T1 weighted MR image, Gd-DTPA enhanced, shows a nasopharyngeal tumour (arrowheads) which is invading toward the left skull. (b) Coronal T1 weighted MR image, Gd-DTPA enhanced, shows a nasopharyngeal tumour (arrowheads) which is invading mainly toward the left skull base.
