[Intrasellar chordoma (author's transl)].

The authors present two cases of intrasellar chordoma and review these tumor's most important characters. This intrasellar localization seems to be very rare. Endocrinological disorders, when observed, leads only to insfufficiency and never to hypersecretion. Final diagnosis is established by histological studies. Their volume is important, so that the recurrence after surgery is common and the middle term prognosis is bad.
