Some au- thors believe that the whole tumor may disap- pear and only acyst remain. In other cases only a microscopical examination will detect a small tumor mass in the walls of the cyst. Spiller has pointed out that the wall of a congenital cyst may be the starting point for a neoplasm, and this possibility should not be ignored. The most common cystic changes found in the brain are due to parasitic growth, the cysti- cercus cellulose and the ecchinococcus. These, however, are so rare in this country that they will not be here discussed. Cysts due to traumatism are recorded, but their genesis is by no means clear. Congenital cysts are rare. They are probably offshoots of the primary cerebral vesicles. Dermoid cysts have been recorded as occurring in the cerebel- lum in several instances. Carcinoma.—Carcinoma of the cerebellum is rare. This form of neoplasm is always second- ary and grows from the dura or in the substance of the brain. Saenger recorded infiltration of the cerebral pia with cancer cells. The possibility of toxic changes must be considered, as it is not improbable that through intoxication caused by
