Inferior sagittal sinus

The inferior sagittal sinus is one of the dural venous sinuses and runs along the inferior (free) edge of the falx cerebri 1. It runs from anterior to posterior, the same as the superior sagittal sinus, and drains into the straight sinus. It receives tributaries from the falx itself as well as some small veins from the medial surface of the cerebral hemispheres.


The inferior sagittal sinus can be absent, as a normal variant. In a study of 204 patients undergoing MR venography there was absence of the inferior sagittal sinus in 14% of patients 2
