Metastasis of intracranial glioblastomas have been described for the f
irst time more than fifty years ago. They are exceptional and seem to
develop clinicaly in less than 2% of cases. In fact, microscopic metas
tasis (necropsic series) of such glioblastomas are much more frequent:
from 6% for supratentorial glioblastomas to 60% in infratentorial one
s; but patients usually die before clinical symptoms appear. The autho
rs report on an intraspinal metastasis which appeared clinicaly four y
ears after the removal of a frontal glioblastoma. The metastasis was s
ubdural, T3. Preoperative radiological data (CT-scan, MRI) evoked a me
ningioma, while surgical findings favoured the diagnosis of neurinoma.
The diagnosis of glioblastoma metastasis was suggested by intra-opera
tive pathological findings, and confirmed a few days later on smears a
nd stains studies.
