The Tentorium Cerebelli: A Comprehensive Review Including Its

WebAs herniation increases, the hippocampus also herniates medially over the edge of the tentorium, compressing the quadrigeminal cistern and pushing the midbrain toward the opposite side of the incisura. WebDescending tentorial herniation (DTH) can be diagnosed by computed tomography. Encroachment upon the lateral aspect of the suprasellar cistern is an early sign of impending tentorial herniation. Actual herniation is evidenced by rotation and shift of the brain stem with consequent widening of the crural and ambient cisterns on the side of the space … Brain tumors are often characterized as supratentorial (above the tentorium) and infratentorial (below the tentorium). The location of the tumor can help in determining the type of tumor, as different tumors occur with different frequencies at each location. Additionally, most childhood primary brain tumors are infratentorial, while most adult primary brain tumors are supratentorial. The location of the tumor may have prognostic significance as well. cfo headhunter
