What Causes Lack Of Balance When Diagnosed With Chiari Malformations?
Considered Chiari, but may be incidental, not cause symptoms.
Detailed Answer:
Hi,
I read your question carefully, reviewed the image, and I can understand your concern.
Technically speaking a descent of 7 mm is considered Chiari malformation (benign tonsillar ectopy is up to 5-6 mm).
That being said it doesn't mean that it is causing symptoms. Most Chiari patients with that degree of descent of the tonsils do not exhibit any symptom and lead a normal life. The fact that there is no finding of syringomyelia, myelopathy or hydrocephalus. The symptoms you describe are subjective should be confirmed by neurological exam.
If there is doubt a special MRI technique, phase contrast MRI with cerebrospinal fluid flow analysis helps understand whether manifestations are due to Chiari.
I remain at your disposal for other questions.
Accident not responsible
Detailed Answer:
Thank you for the additional information.
The answer to your question is no, car accident shouldn't affect tonsillar ectopia, neither its degree nor its symptom manifestation which is due to compression and cerebrospinal fluid circulation alteration.
