The occasional 496 Diseases of the Nervous System association of diabetes insipidus with brain tumor has been men-tioned under the description of that disease. Local Symptoms.—These appear as the result of pressure uponthe brain tissues and depend entirely upon the situation of thetumor, not at all upon its anatomical variety. The pressure maycause only irritation of the nervous tissues, or there may be destruc-tion with paralytic symptoms. It should be remembered that inany case of brain tumor, local symptoms may be entirely depend to a great extent upon the rapidity of the growth ofthe tumor, upon its size, and upon how extensive a localized menin-gitis is present. The diagnosis of the situation of an intracranialtumor from the localizing symptoms is mainly a matter for theexpert neurologist. A general view, however, will be given here ofthe principal localizing symptoms seen with tumors in various partsof the brain. Fig. 2 7g. Sarcoma of the brain in a boy of 2 years Cerebellum.—This situation will be considered first because it isthe most frequent in early life. Tumors of the cerebellum are moreoften seen in later childhood than in infancy, and their situationcan rarely be definitely localized from the sjnnptoms when theyoccur in the first two years of life. The chief sjmiptoms of cere-bellar tumor are vertigo and cerebellar ataxia. Vertigo may often bededuced from the movements of the child, even when the patient isunable to describe his sensations. It may sometimes be strikinglydemonstrated by placing the child upon its feet and causing it toclose its eyes, when a marked swaying of the body will immediatelytake place and the child may fall to the ground. The ataxia seen incerebellar tumor is different from that sometimes seen with a lesionof the spinal cord, and often markedly resembles that of alcoholic Intracranial Tumors 497 intoxication.
