Holocord metastasis from supratentorial glioblastoma multiforme: an uncommon manifestation of a common tumor.

Intramedullary metastasis from primary glioblastoma multiforme (GBM) is a rare phenomenon with a poor prognosis. The rate of spinal metastasis from intracranial GBM has been variably reported to be 0.4-2%. According to a review by Lawton in 2012, there were only 42 documented cases of primary intracranial GBM with spinal metastasis. We present a unique case of early-onset symptomatic holocord metastasis of GBM in a patient approximately 2 months of detection of primary GBM.
