The diagnosis of cysticercosis of the brain during life presents great difficulty because of the variability of its clinical course as well as the absence of characteristic symptoms. The symptomatology of cysticercosis of the fourth ventricle is distinct in its characteristics, and the diagnosis during life is more or less probable; much more complicated is the diagnosis in other localizations of cysticercosis (in the presence of a limited process), and diagnosis becomes impossible when a disseminated racemose form of cysticercosis is present.
The difficulty of diagnosis is generally attributed to the rarity of this special form of disease. In the literature treating of this particular problem, one finds a series of reports in which the writers consider the possibility of the diagnosis slight during life, but, nevertheless, attempt to establish a symptomatology on which the diagnosis may be based with more or less probability. Recently, certain changes in the cerebrospinal
