3D visualization of the neurovascular relationships in a case with left-sided glossopharyngeal neuralgia. With the presented method, we obtain a global overview of the neurovascular relations. We can move the picture in any direction and detect the presence of relevant vessels and cranial nerves and demonstrate the neurovascular compression at the root entry zone of the cranial nerves IX and X. The position as seen during microsurgery (compared to Fig. 2). BA basilar artery, VA vertebral artery, PICA posterior inferior cerebellar artery, V rigeminal nerve, VII and VIII facial and vestibulocochlear nerve, IX glossopharyngeal nerve, X vagus nerve, NVC neurovascular compression
