Lateral Lacunae | Complete Anatomy - Elsevier
WEBThere are usually three irregularly shaped venous spaces, or lacunae, present inside the dura mater, on either side of the superior sagittal sinus. They can be considered as the lateral extensions of the sinus. These include a small frontal, a large parietal, and intermediate occipital lacunae.
Lateral lacunae - e-Anatomy - IMAIOS
WEBDefinition. The lateral lacunae are small openings that communicate with irregularly shaped venous spaces (venous lacunae) in the dura mater near the sinus. There are usually three lacunae on either side of the superior sagittal sinus: a small frontal, a large parietal, and an occipital, intermediate in size between the other two.

WEBLateral lacunae (see fig. 43-11) are venous meshworks within the dura near the superior sagittal sinus, and both the lacunae and sinus occupy the granular pits of the calvaria. The lacunae receive (1) emissary veins, (2) diploic veins, (3) meningeal veins, and (4) occasionally some cerebral veins.

Superior sagittal sinus - Wikipedia
WEBThe superior sagittal sinus (also known as the superior longitudinal sinus), within the human head, is an unpaired dural venous sinus lying along the attached margin of the falx cerebri. It allows blood to drain from the lateral aspects of anterior cerebral hemispheres to the confluence of sinuses.
