case_images: A complete surgical excision of the T8 extramedullary ventral lesion was performed; it was very firm and adherent to the dura [Figure 2].
case_images: (a) H and E stained preparation shows histology typical of a meningioma in the background, with the alien dark staining cells (asterix) representing metastatic involvement by a carcinoma.
