Tumors of the Third Ventricle

TUMORS above the tentorium cerebelli occur among children less frequently than do infratentorial tumors,1 the usual ratio of supratentorial to infratentorial tumors being 1: 2.The cases which we wish to report were taken from the records at the Mayo Clinic. Of 4,318 verified brain tumors, 518 occurred among children from birth through 14 years of age. The cases were reviewed as to type and location of tumor; age, sex, and survival of patients, and symptoms, signs, and roentgenologic findings related to the tumors. The pertinent literature also was reviewed. A total of 190 supratentorial tumors were found, 97, or 51.1% of which were recorded as gliomas according to the classification used by Svien, Mabon, Kernohan, and Adson.2 Fifty-eight of these were astrocytomas; 24, ependymomas; 11, oligodendrogliomas, and 4, neuroastrocytomas. Other supratentorial tumors included 35 craniopharyngiomas, 14 tumors of the pineal body, 12 sarcomas, 12 meningiomas, 9 tumors of the pituitary gland, 7 vascular tumors, 3 epidermoid tumors, and 1 tuberculoma. Keith, Craig, and Kernohan,3 in 1949, reported that 84% of 427 verified intracranial tumors occurring among children were gliomas, and Bailey and associates lb reported that 70% of supratentorial tumors in children were gliomas. The cases of astrocytomas, ependymomas, oligodendrogliomas, and neuroastro¬ cytomas (Fig. 1) will be discussed under the common headings of gliomas.
