case_images: MRI showed a T1-hypointense swelling in the right parietal region with bony defect communicating with the superior sagittal sinus and ventricular dilatation [Figure 2]. MR venography showed a dilated large extracranial vein on the right parietal region communicating with the superior sagittal sinus through dilated diploic and emissary veins [Figure 3]. MR angiography was normal [Figure 4].
