[Brain stem encephalitis].

Using five cases of illness anamnestic, clinical, paraclinical and morphological results of brain stem encephalitis are presented. The usually indistinctive and unspecified liquor syndrome requires a subtly differentiated diagnostic distinguishing between vascular brain stem syndromes and brain stem gliomas. The hypothesis of hyperallergic reaction of the neurovascular system after bland virus infections is discussed. Because of the unclear spontaneous prognosis in this special case of perivenous focal encephalitis with premature paralysis in swallowing and breathing, measures for intensive care should be included in the method of treatment in time.
