Can Arnold Chiari Malformation Be Caused By Whiplash?

I was involved in a car accident in March 30,2011. I went to the hospital for a headache due to the airbag hitting me in the face and extreme back pain. The xrays showed nothing serious and moderate whiplash. I have a friend of mine of whom I went to high school with. I have not seen her since then but recently talked to her. She was diagnosed with a aronald cheri malformation about 6 years ago. She also has been through 8 surgeries since then. Some of which her causes were due to severe whiplash from a car accident she was in. When I told her about my accident, she advised me not to settle but at that time, it was too late,I already did. She also told me that it took 2 years for her symptoms to get to its worst extent and that if it hit me, it would be like multiple sclerosis. I m not sure if she is telling me the truth or not. Is a aronald cheri malformation caused by moderate to severe whiplash?
