Radiation necrosis, which is also known as adverse radiation effect, is problematic from a diagnosis and treatment standpoint, though we have more tools now. MRI and CT show similar changes with enhancement and edema, and to date, imaging has been imperfect.  Since treatment differs for tumor recurrence and radiation necrosis, accurate diagnosis is necessary. New tools are in development.  The treatment of radiation necrosis had been very difficult with limited options, though over the last decade, bevacizumab and laser interstitial therapy has emerged as effective strategies. We will review both diagnostic and treatment strategies in this webinar.
