Histology
MICROSCOPIC DESCRIPTION:
Paraffin sections show a moderately hypercellular meningioma with a broad dural attachment. Tumour cells have uniform nuclear features and are arranged in syncytia and loose fasciculi. No mitotic figures or areas of necrosis are identified and there is no evidence of brain invasion. Tumour is seen to infiltrate between bone trabeculae in specimen.
Sections of decalcified bone tisue show diffuse infiltration of intertrabecular spaces by meningioma.
