It is generally thought that fits are not of usual occurrence in cases of tumors of the cerebellum. It is further agreed that when such episodes do occur the fit is of a tonic opisthotonic character. It is believed that this convulsive pattern indicates a crisis in the progress of the disease, which suggests the presence of a tumor of the cerebellum. Further, as a rule of thumb clinical tenet, it is generally accepted that convulsions of other than the tonic type do not occur in the presence of these tumors (Stewart,1 Bailey,2 Cushing,3 Jelliffe and White,4 Wechsler5).
A survey of 158 cases of verified intracerebellar tumors in patients presenting themselves for treatment at the Hospital of the University of Pennsylvania shows evidence contrary to the general clinical agreement on this subject. Findings in this survey indicate that the incidence of convulsions is apparently higher
