Sir, I had an choroidal plexus AVM in the right temporal horn of the lateral ventricle. Due to surgical complications, I had underwent Gamma knife radiosurgery on May 2017. And they asked to report after 6 months with MRI. In the MRI of brain, there is impressions said that, *A case of right temporal AVM-post Gamma knife surgery *Few residual tortuous vessels in the right media, posterior, temporal lobe with adjoining gliotic changes. After seeing this report and MRI doctors said that AVM is still in that size no enlargements and shrinking takes some time. I was early taking eptoin tablets. Due to some side effects like in-activeness they given levipil 500 mg tablets instead of eptoin. Is there any side effects associated with this. How long do I need to take these tablets. I also feel pulse in my forehead sometimes severe pulse which cause headaches. And elevated heart beat. What's the reason for it. Does this gliosis affects my memory. Please help me in detail.
