"Meningothelial meningiomas most closely resemble arachnoid cap cells and are characterised by sheets, whorls or syncytia of neoplastic cells which have round or oval centrally located nuclei with dispersed chromatin, smooth nuclear profiles and small indistinct nucleoli. They also sometimes demonstrate eosinophilic cytoplasmic invaginations (a.k.a. intranuclear pseudoinclusions) 2-3. Lobules of the tumour are separated from each other with collagen sheets 3."
