Meningioangiomatosis: A Case Report and Literature Review Emphasizing Diverse Appearance on Different Imaging Modalities

Figure 5

Histologic sections (200x) stained with hematoxylin and eosin (H&E) demonstrate greatly thickened vascular walls (a, arrow) within the cerebral cortex that are concentrically surrounded by meningioma cells, typical of meningioangiomatosis. Pyramidal cells (a, arrowhead) of the architecturally distorted cortex are noted between thickened vascular structures. In other regions (b, arrow), vessels showed fewer surrounding meningioma cells, but greater degrees of collagen, indicating substantial chronicity. Psammoma bodies (b, arrowhead) were scattered throughout.
