title: Frontal lobe perivascular schwannoma. Case report.
abstract: A 15-year-old youth presented with a history and computerized tomography picture of subarachnoid hemorrhage. Conservative management was undertaken after failure to demonstrate an aneurysm. Reevaluation and operation 15 months later disclosed a firm leathery schwannoma intimately related to the frontal lobe and extending into the cortex in the Virchow-Robin spaces.
