Among the less frequently observed tumors of the brain in both adults and children is papilloma of the choroid plexus. Because such a tumor rarely gives rise to definite localizing signs, it has usually been discovered at postmortem examination or during intracranial exploration, and at times it has probably been overlooked altogether.
Pathologic studies have established the preponderantly benign nature of the tumor. Successful surgical removal in an adult of 47 years was reported by Perthes1 in 1919, and in an adult of 55 years, by Sachs2 in 1922. Since the introduction of ventriculography by Dandy,3 a method has been available, when indication for its use is recognized, for preoperative localization of the tumor. Of thirty-four true cases that we have found reported in the literature, fourteen were in children below the age of 15 years. Scant mention is made of them in pediatric literature. Harvey Cushing
