Transverse sinus

The transverse sinus is one of the dural venous sinuses and drains the superior sagittal sinus, the occipital sinus and the straight sinus, and empties into the sigmoid sinus which in turn reaches the jugular bulb.

The two transverse sinuses arise at the confluence of the three aforementioned sinuses at the torcula herophili or confluence of sinuses.

Highly variable anatomy. For example one study:

  • 20% aplasias of the left sinus
  • 39% hypoplasia of the left sinus
  • 31% symmetric
  • 6% hypoplasia of the right sinus
  • 4% aplasias of the right sinus
