The confluence of sinuses (Latin: confluens sinuum), torcular Herophili, or torcula is the connecting point of the superior sagittal sinus, straight sinus, and occipital sinus.

Mar 12, 2018 · We describe two representative cases of the right-dominant type with a non-communicating left TS (shown in Fig. 2 a, a′) and the left-dominant type with a partially-communicating right TS (shown in Fig. 2 b, b′). In the former case, the …

The confluence of sinuses, torcular herophili, or torcula is the connecting point of the superior sagittal sinus, straight sinus, and occipital sinus. It is found deep to the occipital protuberance of the skull. Blood arriving at this point then proceeds to drain into the left and right transverse sinuses. The superior sagittal sinus often drains into (either exclusively or predominantly) one ...

Torcular dural sinus malformations (tDSMs) are rare vascular malformations that present in fetuses and infants. Existing data on prognostic imaging features, as well as the associated morbidity and mortality, are limited and variable.
