abstract

  • Abstract The cerebral edema, as judged by computed tomographic scan, associated with supratentorial meningiomas was assessed in 55 cases. No relationship to the occurrence or the degree of edema could be established with respect to meningioma location, histological type, tumor vascularity, cellularity, number of mitotic figures, necrosis, calcification, or cortical invasion. The larger the meningioma, the more likely the presence of and the severity of cerebral edema. The edema is a significant factor in the occurrence of clinical signs and symptoms. A biopsy of cerebral cortex and white matter underlying a transitional meningioma in a patient with associated cerebral edema demonstrated perivascular astrocytic end-feet swelling in the cortex and considerable extracellular fluid in the white matter. The ultrastructural appearance is similar to that seen with primary and metastatic brain tumors and with experimental vasogenic cerebral edema.
