title: Glioblastoma multiforme and the meningeal syndrome.
abstract: Brain tumors rarely may produce acute steile meningitis (the meningeal syndrome) resulting from the spillage of blood, lipid products of tumor necrosis, or malignant cells into the cerebrospinal fluid (CSF). The frequency of the associated meningeal syndrome is a function of tumor type and of the tproximity of tumor necrosis to the ventricles. The meningeal syndromes of lipid-induced chemical inflammation are seen most commonly with epidermoids, craniopharyngiomas, and infarcted pituitary adenomas. I report a patient with the rare association of the meningeal syndrome with glioblastoma multiforme. The lipid irritants of glioblastomas and craniopharyngiomas are similar chemically and can be detected in the CSF. The anti-inflammatory and immunosuppressant properties of steroids provide a rational basis for their efficacy in treatment of the syndrome.
