Papilloma of the choroid plexus is a rare tumor; no single author's published experience encompasses more than 12 instances. For this reason alone it seems justifiable to collect the isolated reports, since the frequency of diagnosis and surgical treatment of tumors of the brain is ever increasing and since there are few persons with a neurosurgical or neuropathologic experience extending over a period of five years who have not had contact with at least 1 papilloma. This paper represents a collection of the 80 odd published case reports of papilloma of the choroid plexus, together with some emphasis on incidence, sites of origin, inferences as to growth characteristics, pathologic picture—with emphasis on the known seeding characteristic—and summarized surgical experience.
Cushing's series of 2,023 tumors of the brain contained 12 papillomas of the choroid plexus; Elsberg's series of 878 contained 2; Tooth's series of 258 contained 3, and Peers's series
