Summary
The location of the choroid arterial point as well as of the copular venous point with reference to a line, dealing with the anatomical structure at the level of the cervicooccipital joint, was found to be a quick and accurate method for the diagnosis of tonsillar herniation. The application of this method has the advantage of giving the location of the choroid arterial point, and a control of the venous time of arteriography by the location of the copular point.
