case_images: A brain magnetic reasoning imaging (MRI) showed a large expansile lytic mass lesion arising from the skull vault in the frontal-parietal region with multiple internal septa, and a brain magnetic reasoning venography showed an occluded anterior segment of the superior sagittal sinus secondary to lesion invasion [Figure 2].
