Abstract

Intraosseous schwannoma is a rare benign nerve sheath tumor comprising < 1% of bone tumors. Relatively common locations for this tumor include the skull and mandible, and, to a lesser degree, the spine and sacrum. Intraosseous schwannoma involving the appendicular skeleton is exceedingly rare. The clinical and imaging presentation, as in this case, is nonspecific and includes pain in the setting of a lytic bone lesion. The first step in management is bone biopsy that often produces greater than expected pain. Definitive management is surgical.
