Radiosurgery is the precise application of focused radiation to a targeted volume area within the brain, which has been identified on MRI. With recent advances, radiosurgical treatment is now being evaluated as an alternative treatment to öpen resective surgery for intractable epilepsy. Recent studies suggest that radiosurgery may be an effective and safe treatment for medically intractable epilepsy associated with mesial temporal sclerosis, cavernous malformations, arterivenous malformations, hypothalamic hamartomas and can help reducing the frequency of epilepsy in certain types of diseases.
