Spinal Dissemination of Intracranial Glioblastoma in Bevacizumab Era: a Potential Bevacizumab-induced Mechanism.

Spinal metastasis, a devastating neurologic complication of intracranial glioblastomas is not as uncommon as initially thought. It varies from 25% in supratentorial glioblastomas to 60% in infratentorial glioblastomas. The underlying pathogenesis spinal spread of high-grade gliomas is still unclear. To date, no causal responsibility of Bevacizumab (BEV) was noted. Here, we report for the first time, a case of thoracic intramedullary metastases from a cerebral glioblastoma pre-treated with BEV. A critical and exhaustive review is provided.
