A 50 y.o. male presented with a right parietal tumor which was a glioblastoma on stereotactic biopsy. He was treated by radiation and steroids, with clinical improvement. Four months later, he presented with a left preauricular mass and cervical lymphadenopathy. CT scan showed destruction of the left mastoid and filling of the left tympanic cavity. One month later, he suffered progressive dyspnea. Chest X ray showed a mediastinal mass on the right side and numerous bilateral interstitial opacities in the lungs. A bronchial biopsy was inconclusive. His general condition worsened, and he died. Postmortem showed continuous neoplastic infiltration of the left part of the base of skull, extending into the neck. Numerous metastases were present in mediastinal lymph nodes, lung parenchyma, pleura and pleural aspect of the diaphragm. There were no subdiaphragmatic metastases. Neuropathological examination confirmed a poorly differentiated highly malignant glioblastoma with severe necrosis involving the internal part of the parietal lobe extending to the dura mater of the convexity and falx cerebri with invasion of the superior longitudinal sinus which was entirely occluded. The biopsy scar was not infiltrated. Visceral tumors were morphologically identical to the brain tumor. They were strongly GFAP positive and cytokeratin negative. Extraneural metastases of glioblastoma in the absence of surgery are uncommon in adults. Involvement of the dura mater and/or superior longitudinal sinus is an almost constant feature. In our case, this may have led to invasion of the base of skull and secondary regional, lymphatic, and hematogenous spread.

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.

A 30-year-old man presented with weeks of progressive headaches, imbalance, and aphasia. Brain MRI revealed an enhancing left frontal mass (figure 1, A and B). Chest imaging revealed mediastinal and hilar adenopathy (figure 1, C and D). Metastatic cancer was initially suspected, but pulmonary lymph node aspiration revealed sarcoidosis (figure 2A). Subsequent brain biopsy revealed glioblastoma (figure 2B).
