  • (AKA Neurolemmoma)

    • Can be pretty much anywhere (even in the brain)

      • When they are in the brain, they are most commonly attached to CNVIII (called acoustic neuromas and are common in people with neurofibromatosis type II)

      • When they arise from the spinal cord they typically come from the dorsal roots

    • Very well circumscribed and may even be encapsulated; benign

    • Generally not attached to the nerve they arise from, so they can be surgically separated

    • Look for Antoni A and Antoni B areas and Verocay bodies microscopically

    • Antoni A areas are very cellular and Antoni B areas are poorly cellular

    • Verocay bodies are a bunch of cells that butt up against a pale, less cellular area
