[Bone metastasis from a glioblastoma: An unusual course!]. / Métastase osseuse d'un glioblastome: évolution inhabituelle!

Extraneural diffusion of glioblastoma is very unusual. Extracranial metastases generally occur after craniotomy or a long survival time. Metastases usually involve the lungs, pleura, lymph nodes and occasionally the bone. We report herein a case of bone dissemination occurring 18 month after the initial diagnosis and treatment of supratentorial glioblastoma.
