case_images: T1 weighted post contrast magnetic resonance imaging depicting the destructive nature and invasion of the vascular lesion; although it is closely associated with dura and superior saggital sinus, there is no evidence of parenchymal invasion. Digital Subtraction Cerebral Angiogram (right sided image) further characterizing the vascular lesion; arterial supply with fistulization from the ophthalmic artery and also some lesser arterial supply from the superficial temporal arteries bilaterally

case_images: Heterogenous contrast enhancement on magnetic resonance imaging [Figure 1] further defined the lesional dural involvement and invasion into the superior sagittal sinus sparring cerebral parenchyma.
case_images: These images detailing of the preparation and incisional marking. The lesion's sheer size can be appreciated
