Abstract:
Parachordoma is a rare tumor, with fewer than 100 cases reported. We present an unusual presentation of a long tumor tracking along the median nerve, with regional metastasis to the axillary nodes in a 67-year-old woman. The tumor extended from the wrist proximally along the forearm to the elbow, coursing intraneurally along the median nerve. We present this case due its rarity, interesting radiographic appearance, and atypical presentation.
