We reviewed 11 consecutive patients with an antemortem cytologic diagnosis of meningeal gliomatosis.In three patients,meningeal gliomatosis was diagnosed before surgical resection of the glioma.Three of five patients with anaplastic astrocytoma and one with oligoendroglioma improved with treatment.Patients with glioblastoma multiforme did not respond and had a median survival from the diagnosis of meningeal gliomatosis of only 8 weeks.Meningeal gliomatosis can be an early finding in gliomas.Treatment response is probably related to tumor histology and grade. |
