Chordoma of the Basiocciput and Basisphenoid: Report of Four Cases

High activity iodine 125 endocurietherapy for recurrent skull base tumors

“…A few months later, four more 1 millicurie radon seeds were implanted, and the tumor mass was reduced to 20% its original size. 43 Zoltan and fen ye^^^ reported a case of clival chordoma treated by means of stereotactic implantation of five "yttrium seeds of 5 to 6 millicurielseed. The patient was symptom free at 9 months follow-up.…”

Interstitial Irradiation of Skull Base Tumours

“…The first reported chordoma treated by this method was in Montreal in 1938. 50 A chordoma extending into the nasopharynx was implanted with six 1 mCi radon seeds combined with 4,000 rad external radiation. A few months later, four more 1 mCi radon seeds were implanted, ultimately resulting in the shrinkage of the nasopharyngeal portion of the tumour to one fifth its original size.…”
