Meningiomas don’t always cause any symptoms at all — many are discovered incidentally, during an MRI or CT scan done for another reason (such as after an injury or accident). If the tumor is not causing symptoms and does not show signs of growth on a follow-up scan, it may not need to be treated at all.
