Two years ago I had a brain MRI (I ve had another, more recent one but don t have immediate access to it) and the report states, Mild heterogeneity of the clivus is within normal limits . I was 60 years old at the time. I have been getting migraines with aura for 20 years, but they have recently become more frequent and not always on the left side of my forehead. They change location. I was told my most recent MRI - approximately 1 month ago, was normal. I was told many years ago that I had a cyst on the Pineal Gland, but that it was fairly common. My concern is the quote above re: the clivus. Should I be concerned, or at 62 years of age is that normal?
