  • Abstract
  • Look Inside

Tentorial herniation plays one of the most im-portant roles in the fate of neurosurgical patients, so the detection of neurological pressure cone syn-dromes is essential in the clinical practice. However, when the herniation has once developed, prognosis of the patient is becoming often and suddenly worse, it is necessary to make an early diagnosis against the tentorial herniation to have a satisfied treatment. It has been pointed out that the morphological changes of cisterna ambiens (in air study) and some blood vessels surrounding the brain stem (in angiography) call demonstrate the presence of the herniation. The author had some comparisons among those neurorad-iological changes of tentorial herniation and had taken special considerations on the changes of the basilar vein of Rosenthal in accounts of early diagnosis of the herniation.

The basilar vein runs on the lower surface of temporal lobe surrounding the brain stem, and gently ascends in the cisterna ambiens posteriorly to the thalamus and flows into the great cerebral vein of Galen. In conclusion, it was find out that the stretch-ing in the lower base of this basilar vein in the lateral cerebral phlebogram might be a valuable find-ing for the early diagnosis of downward tentorial herniation. An emphasize should be put on that this finding could be observed before the clinical mani-festation of pressure cone syndromes.
