Lateral lacunae of superior sagittal sinus

Lateral expansions of the superior sagittal sinus of the dura mater, often increasing in width with advancing age until, in very old people, they may extend two centimeters lateral to the midline; the endothelium-lined lumens of the lacunae are usually reduced to a spongelike labyrinth by numerous arachnoid granulations and dural trabeculae.
