ABSTRACT
The term confluence of sinuses, in modern parlance, “refers to the dilated posterior end of the superior sagittal sinus, to one side (usually right) of the internal occipital protuberance, where it turns to become a transverse sinus. It also connects with the occipital and contralateral transverse sinus” (Williams et al., 1995). Beginning in centuries past, and as time went by, the confluence of sinuses was called Herophilus’ press, torcular, torcular herophili, sinus confluens, or fourth sinus.
