Multiple Meningiomas of Different Histologic Subtype: Case Series and Literature Review

Meningioma is the most common primary CNS tumor. Multiple meningiomas (MM) are rare outside of neurofibromatosis, and MM of different histologic subtypes is even less common. Here we describe two cases of MM with different histology and review the literature on MM. Two hundred twenty five publications on MM were found through a Medline search. Only six describe meningiomas of different histologies. Our series is the first that we know of to describe MM that includes the secretory subtype.
