Figure 2: Magnetic resonance venogram (a) and left internal carotid angiogram in venous phase (indirect venography), frontal (b), and lateral (c) views demonstrating the diverticulum at the junction of right transverse–sigmoid dural sinuses (arrow), measuring 9 mm × 4 mm. Magnetic resonance venogram showed mild prediverticular narrowing in distal transverse sinus (curved arrow in a). However, there was no significant pressure gradient at this site during direct venography, indicating that there was no significant stenosis
