MICROSCOPIC DESCRIPTION: The sections show a moderately cellular meningioma with attached dura. The tumor comprises whorls and nests with psammoma bodies. The tumor cells have ovoid nuclei but with no nuclear pleomorphism. Mitoses are inconspicuous. There is no tumor cell necrosis. Many blood vessels are present in the background and they have prominently hyalinised walls. Microcystic change is noted. Brain parenchyma is included in the biopsy and there is no evidence of brain invasion. No atypical or malignant change is identified.
