A case of posterior interosseous nerve paralysis at the level of the Frohse arcade, caused by an intramuscular myxoma, is reported. Review of the literature shows this to be an exceptional presentation of this tumor as a cause of a compressive peripheral neuropathy. Twelve months after surgical treatment, total neurological recovery was observed.
