Figure 1. Sagittal T1-weighted MR images show the measurements of structures related to posterior cranial fossa morphology. The numbers represent the measured distance: 1. Tonsillar herniation; 2. Distance from pons to FM; 3. Distance from corpus callosum to FM; 4. Distance from Fastigium to FM; 5. Distance from pons to dens axis; 6.Distance from corpus callosum to dens axis; 7. Distance from Fastigum to dens axis; 8. Distance from dorsum sella to dens axis; 9. Clivus length; 10. Distance from dens axis to posterior margin of FM; 11. Clivus canal angle (Weckenheim line- posterior vertebral body line).
