442 DISEASES OF THE BRAIN 



The symptoms produced depend upon the location of the 

 tumor and the degree of intracranial tension. They may 

 be those of paralysis, muscular incoordination, rolling or 

 turning movements, deafness or blindness. Unless the 

 symptoms indicate that the tumor is located near the cortex 

 or involves the membranes covering the brain, treatment, 

 which is purely surgical, should not be attempted.
