[Nonaneurysmal vascular pressure lesions of the cranial nerves (author's transl)].

Four cases of facial spasm and 1 case of oculomotor paresis are described. The source of the disorder in all 5 cases is mostlikely not an aneurysm of the vessels of the base of the brain. The literature is discussed and thereby it is shown that mechanical disturbances of other cranial nerves (II, V, VI, IX, XII) can be caused by similar vascular (nonaneurysmal) abnormalities.
