Tumors of the Pineal Gland

In this paper two cases of tumor of the pineal gland are reported, and an endeavor has been made to summarize all such cases in the literature in order to determine the most frequent signs and symptoms. The most comprehensive summaries at present in the literature are those of Bailey and Jelliffe, in 1911, who reviewed fifty-nine cases, and of Seigneur, in 1912, who described sixty-five tumors of the pineal gland. In the present paper 113 cases are tabulated with respect to microscopic picture, symptoms and incidence according to sex and age. Valuable assistance in the preparation of this report has been rendered by Dr. G. Y. Rusk, who furnished the pathologic material, and by Dr. H. C. Naffziger, from whom the clinical data on the first case were obtained. REPORT OF CASES Case 1.—History.—The patient, a white woman, aged 49, entered the neurosurgical service of the University
