The Lumbosacral Dural Venous Sinus: A New Discovery with Potential Clinical Applications

Our study identified a dural venous sinus located in the dorsal lumbosacral region and near the midline. We suggest this structure be called the lumbosacral venous sinus. Although the function of such a sinus is speculative, knowledge of its presence might benefit those interpreting imaging of this region, especially with regional pathology such as dural arteriovenous fistulas.
