title: [Massive orbital osteolysis by a chordoma. Report of a case and review of the litterature (author's transl)].
abstract: Clinical, radiological and anatomical description of sellar chordoma giving, on a sixty seven years old man, an unusually large tumoral exophthalmos, a massive orbito-sphenoidal osteolysis and a chiasmatic syndroma. Discussion stresses the topographic data of chordoma in connection with the embryonal chordal cell rests. Patterns of evolution and neuro-ophthalmologic symptoms of cephalic chordoma are studied with the literature facts. Morphologic criteria, specifical ones and those differential diagnosis, are exactly scheduled.
