상완신경총의 신경초종

Neurilemmoma is a benign nerve tumor which has been described as painless mass and is usually discovered incidentally. Neurilemmoma of the brachial plexus is rare lesion.

The initial presentation is usually a painless, supraclavicular mass (level V), but patient has a tingling sensation in the affected forearm. We operated 3 cases of brachial plexus neurilemmoma under microscope and intraoperative nerve action potential monitoring without neurologic complication. Recently we experienced rare cases of neurilemmoma arising from brachial plexus and so we report our cases with a brief review of literature.
