Cerebral mixed tumour: osteo-condrosarcoma--glioblastoma multiforme.
A 49-year-old woman had a left frontal expanding mass with calcified areas. A craniotomy and resection of the mass were performed. Histological sections showed a mixed tumour: osteochondrosarcoma-glioblastoma multiforme. The absence of previous irradiation and its location, deep in the frontal lobe and apparently unattached to the meninges, add to the rarity of this association. A brief discussion concerning the presence of osseous or cartilaginous areas in brain tumours and the problem of cerebral mixed tumours follows the description of the case.
