The straight sinus may be doubled or tripled. In 56 human cadavers, Magden found the straught sinus in 26.7% of cadavers to be doubled, being either median in position (one superior to the other) (17.8%) or paramedian (both lying on side of the midline at the junction of the falx cerebri with tentorium cerebelli (8.9%). In two cases (3.5%) the straight sinus was triple, being either median in position or paramedian.
