MRI demonestrating a hemogenous avidly enhancing and well-defined mass at the inferior aspect of the vein of Galen cistern. There is a left sided enhancing mass which almost certainly represent an intracanalicular acoustic schwannoma.
Meningiomas that arising from the falcotentorial junction (the junction of the dural folds of tentorium and falx cerebri) occupies the quadrigeminal cistern by protruding anteriorly and inferiorly.
Solid nodular mass with intense contrast enhancement and intracanalicular component and widening of porus acusticus represent acoustic schwannoma
In a relatively young patient having both tumors raises the possibility of neurofibromatosis type 2 (NF2).
