case_images: Another extramedullary mass was located between D5-D6 vertebral levels, extending to the right D5-D6 foramen [Figure 2].
case_images: After D4 laminectomy, the mass was removed (a); the lesion was completely extradural (a); the underlying dura mater was intact (b)

case_images: Extradural masses were completely removed and dural basements were cauterized [Figures 3 and 4].
case_images: After D5 left partial hemilaminectomy, the mass was removed, it was completely extradural (a); the surgical field at the end of meningiomas exeresis: the dura mater was comletely intact (b)

case_images: Histology. Hematoxylin and eosin staining (a) shows the histologic pattern of meningothelial meningiomas and polygonal cells with ill-defined cytoplasm, immunohistochemically EMA+ (b), with low Ki67 proliferation index (c)
