The literature pertaining to tumors of the third ventricle is largely concerned with the various clinical syndromes, postmortem observations and histologic studies of the lesions and, only recently, with preoperative diagnosis and surgical removal of the new growths. It is not my purpose in this paper to give a résumé of the literature on the numerous clinical syndromes caused by tumors of the third ventricle, which have been so ably described by Weisenburg and by several others.1
