摘要: Resume La radiochirurgie des oligodendrogliomes n’a pas de specificite. Elle s’inscrit plus globalement dans le traitement gliomes ou ses indications n’ont encore beneficie d’une evaluation rigoureuse. Neanmoins, empiriquement, compte tenu contraintes limitees pour patient et resultats radiologiques cliniques encourageants, la plupart equipes qui en ont pratique proposent deuxieme intention, lors reprise evolutive formes malignes. Exceptionnellement, certains benins taille reduite, parfaitement definis neuro-imagerie, peuvent etre irradies cas d’impossibilite d’exerese chirurgicale. permet d’envisager un controle local du gliome, regle transitoire, une dose a l’isodose reference comprise entre 15 18 grays. L’un problemes cles est definition limites lesion. Dans courant gliome malin, les ne sont pas, souvent, accessibles depit progres neuro-imagerie. En pratique, zone nodulaire consideree comme active sur l’IRM, soit prise contraste, compte. Sa grande dimension doit l’ordre 35 mm 40 mm. s’adresse qu’aux patients dont mobilite fonctions superieures faiblement, alterees. L’optimisation cibles (zones actives particulier), part, etudes prospectives randomisees, d’autre devraient permettrent mieux definir technique.
