case_images: The purely extra-axial lesion was isodense with brain tissue, and only the inner surface took up contrast, likely due to the involvement of the dura [Figure 1].
case_images: Intraoperative findings of the lesion. (a) The tumor was noted to have a well-demarcated fibrous outer capsule, with erosion of the pericranium, and tight dura adherence; (b) the lesion received its main blood supply from the engorged middle meningeal artery; (c) superior view of the lesion; (d) inferior view of the lesion
