  • Figure 1
    Axial MR-image showing segments of the facial nerve

    REZ: root exit zone (nerve exits from pons). AS: attached segment (nerve adheres to pons). RDZ: root detachment zone (nerve detaches from pons). TZ: transition zone (transition from central to peripheral myelin). CZ:...

    Neurovascular conflict between the facial nerve and the PICA

    Neurovascular conflict between the facial nerve and the posterior inferior cerebellar artery (PICA) at the vulnerable transition zone, where central glial myelin transitions into peripheral Schwann cell myelin.
