Brain Stem and Tentorial Notch

  • M. Nadjmi
Conference paper


Tentorium cerebelli is one of the most significant and clinically important anatomic structures of the brain. Tentorial roof corresponds to the great vein of Galen. This is where the tentorial notch begins, subsequently ending on the level of the posterior clinoid process. In the computed tomogram the two lateral tentorial walls are usually cut axially. On the roof level they have the shape of “V” or “Y”, whereas the basal cuts diverge. The intersection of two walls is always the Sinus rectus. The region between these two lines is infratentorial, laterally it is supratentorial, and ventrally there is the tentorial notch.
