Figure 9. Neurovascular compression and trigeminal neuralgia in a different patient. (a) 3D-FISP sequence reconstructed in the sagittal oblique plane to show the right trigeminal nerve. There are two vessels in contact with the upper and lower aspects of the nerve (arrows). (b) An axial reconstruction may occasionally be helpful. One of the vessels shown in (a) is in contact with the lateral surface of the right trigeminal nerve (arrow). The other vessel seen in (a) lies posterolateral to the arrowed vessel on this section.
