The parietal foramina are present in 60% of cases. It is commonly unilateral, rarely multiple. The human parietal foramen transmits an emissary vein (Santorin's vein), which connects the occipital veins with the superior saggital sinus. It also transmits a minute anastomosis between the middle menigeal and occipital arteries. (R. meningeus A. occipitalis)
