  		FIG 1. MR venography of the cerebral sinuses and its variations in the torcular herophili.

A, Right and left transverse sinuses are of similar caliber. Both the superior sagittal and straight sinuses drain into the torcular herophili.

B, Flow void is seen in left transverse sinus. The superior sagittal and straight sinuses drain into the right transverse sinus.

C, Right transverse sinus is absent. The right sigmoid sinus and internal jugular vein are atretic. The superior sagittal and straight sinuses drain into the left transverse sinus and then into the sigmoid sinus and left internal jugular vein. Venous plexus are seen around the foramen magnum.

  		FIG 2. Selective 2-cm midline band is applied to the maximum intensity projection of the MR venography to exclude cortical veins. Lateral projection of the maximum intensity projection image shows the bulbous prominence of the vein of Galen (arrow).

  		FIG 3. MR venograms of the torcular herophili associated with occipital sinuses.

A, Occipital sinuses (arrows) are present on both sides, which serve as alternative drainage pathways from torcular herophili to internal jugular veins. This is associated with absence of both transverse and sigmoid sinuses.

B, Right occipital sinus (arrow) is associated with atretic right transverse sinus.
