Intracranial dissecting aneurysm. Report of a case.
The case of a 47-year-old man who died one month after a history of paroxysmal occipital headaches, vertigo, vomiting, weakness, and sweating is presented. The death was due to a pontine softening caused by a subintimal dissecting aneurysm of the two vertebral, the basilar and the right posterior inferior cerebellar arteries. No etiological factor of the illness could be found. The clinical signs resembled those of a flap-valve tumor of the IIIrd ventricle.
