PRIMARY LEPTOMENINGEAL ASTROCYTOMA - CASE-REPORT

Gliomas very rarely arise from the leptomeninges. They can be both sol itary and diffuse, and histological examination reveals mostly astrocy tic tumors. The authors report a case (the 12th reported in the litera ture) of a solitary primary glioma of the leptomeninges in a 79-year-o ld man who presented with repeated seizures. A magnetic resonance imag e revealed an ill-defined enhancing lesion in the cerebral meninges. A utopsy examination showed a poorly demarcated astrocytoma in the sylvi an fissure infiltrating the adjacent subarachnoid space. The literatur e concerning primary leptomeningeal glioma is reviewed.
