Primary intracranial papillary meningioma: Analysis of factors of prognosis and systematic review.

Objective: Papillary meningioma is rare and displays an aggressive clinical behavior with poor prognosis. Therefore, we performed an extensive literature review to evaluate the adverse factors and treatment strategy of survival.

Method: We performed Ovid, Medline, Embase, Pubmed, Web of Science and Cochrane database queries for articles published between 1938 and 2019 with the search term "WHO grade III meningioma" or "papillary meningioma" and "central nervous system", "cerebral", or "intracranial".
