Abstract
Extraneural metastases from glioblastoma multiforme are rare. Spread to the extracranial head and neck may be evident on routine follow-up images of the original lesion. We present two cases, one with documented metastatic adenopathy in the head and neck from glioblastoma and the other with probable metastatic disease in a lymph node in which biopsy was not performed, and discuss probable mechanisms of extraneural extension of this tumor.
