Meningiomas - multiple posterior fossa

Discussion:

Some patients, even in the absence of prior radiation or NF2 have a predilection for developing meningiomata. In this case one must assess the left lesion just adjacent to the IAC carefully as were this to represent an acoustic schwannoma then the diagnosis of NF2 would be suspected (unusual in this age group). 

Meningioma confirmed histologically.
