Question: Hi! I am 35 years old and have been experiencing vertigo, dizziness, balance issues and blurred vision after a car accident that occured 2 months ago. They did an MRI of the brain and it noted that a mega cisterna magna is noted but that the ventricles and subarachnoid spaces are appropriate for my age. Ive had 2 mris of the brain in the past prior to this accident for headaches and both those mris never noted mega cisterna magna. My neurologist doesnt seem concerned and in fact didnt even mention it as o found it when i read the results.

He claims the dizziness, vertigo is all related to the whiplash injury and the herniated disc i have in my neck.

I just want to be sure this result is not indicative of a brain cyst. In addition since my prior mris of the brain did not show this i was wondering could this be a result of the accident?

The neurologist did say that this radiologist tends to over read mris

Your input is appreciated!

Best, XXXXXXX

Brief Answer:
Mega cisterna magna is a normal variant.

Detailed Answer:
Hi Ms XXXXXXX

Thank you for posting your query.

I have noted your symptoms and MRI brain findings.

I would agree with your neurologist that there is no need to worry about the finding of mega cisterna magna, as it is a normal variant, found in many normal people.

There is no need to do anything about this, as it does not produce any symptoms.

There is no cyst in your brain.

Your vertigo and other symptoms would gradually improve with symptomatic treatment.

I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.

Wishing you good health,

Thank you so much! I greatly appreciate your feedback. I will absolutely give you a good recommendation.

So I would assume that the accident did not cause the mega cisterna magna and if it was there before it was never mentioned on other mris correct?

Yes, I agree with you.

Detailed Answer:
Thank you for getting back.

Yes, I fully agree with you that the accident did not cause mega cisterna magna and it was there prior to the accident also, just that earlier radiologists did not mention it in the reports.

I had whiplash incident in October 2010 but I realised that time my injury will get better and heal later but didn t and I was up and down worse almost one year after incident such as dizziness , headaches , neck and back aching. The bus hit from behind was not very high speed but was the double decker bus so I can felt the very high force within seconds my neck suddenly jerk forward then backward. I didn t see I got injury that time and pain was developed from middle of the night and my whole body was started aching badly. Actually my lower back pain middle and left side are currently getting worse and it was gradually develop since from incident. I also had both sides shoulder , arms, chest, bullocks, ribs next to chest got pain tender points currently. Especially lower back is more painful and uncomfortable when sitting or lay down currently. Do you think, I got serious injury my spine? From my neck to middle back along to lower back had pains muscles tenderness since from injury until current. Do you know why these back muscles pains doesn t go away? I had done MRI scan to T6/T7 in mid 2011 that was normal but couple of last few weeks ago my blood test result was antinuclear positive. Do you think that antinuclear positive results are related to whiplash injury and causes even my health worse? I m also still waiting further MRI scan for lower back that they never scan it after the incident. I didn t have any health and lower back pain problems berfore the accident. Please advice.

I had a fall down stairs and went to hospital. I was diagnosed with whiplash, possible mild concussion. They did a full X-ray of my spine with no fractures. I was then admitted to hospital the next day with bleeding from the bowel. I had a camera inserted into the bowel with no problem diagnosed. This occurred last Saturday and Sunday. I am a rower. The first time I rowed being Thursday I vomited. I raced on Friday and vomited 5 times at the 500m mark. My vision is blurred and I got an intense headache like my head was going to explode. What is wrong with me?
