I just had my repeat MRI for my meningiomas. They didn't grow any at the 3-month mark, but are recommending Gamma knife to control them now, while they are controllable. The primary tumor is 2.5 cm, and the other three masses are about 0.7 cm each. My primary meningioma has affected my hearing and some dizziness. Have others had dizziness from their meningiomas? I would welcome any conversations on Gamma Knife as well.
