Hi… a family member had a meningioma treated at Mayo Rochester last August with the gamma knife. The procedure was a success, but she experienced significant post-procedure swelling about 4 months later and ended up having to go to the emergency room with a multitude of neurological symptoms. The steroids she had tapered off of were needed to be added back to control the swelling. She has had several more bouts of neuro symptoms each time the steroid was reduced. She is just coming back out of the hospital and rehab again on a new maintenance steroid plan. Her tumor was small enough to be a good gamma knife candidate. Not sure what the long-term plan will be. Hoping to find just the right dosing of steroids to control the swelling with out any significant side effects. She is a very young 81 years old.
