title: Compressive optic neuropathy due to orbital metastasis of a sacral chordoma: case report.
abstract: A 44-year-old man presented with unilateral proptosis and progressively deteriorating vision of his left eye over a 2-week period. He had a history of recurrent sacral chordoma for 1 year that had previously been treated with combined surgical excision, chemotherapy, and radiation therapy. MRI showed compression of the optic nerve by an orbital mass that proved to be an orbital metastasis of his sacral chordoma. The tumor mass was excised subtotally, and adjuvant orbital radiation therapy was administered.
