What causes persistent mild dizziness?

I was diagnosed 4 years ago with a 11cm X 7cm posterior arachnoid cyst and had a VP shunt put in to regulate its size. My symptoms improved until one year ago when I began having slight dizziness every time I move my head or lay down. The only remarkable thing found on my MRI w/ & w/o contrast was the following:Ventricles - The fourth ventricle has increased in size since the previous examination (1.5 years apart). This is likely related to volume loss and ex vacuo enlargement. Clinical correlation is recommended.Should I see a neurologist about this? My neurosurgeon said nothing was wrong with my shunt and didn t understand why/or cared about my daily dizziness. What do you think is causing this?

Neurologist 's  Response
Hello!

My name is Dr. Aida and I am glad to attend you on Healthcaremagic!

The fact that there is increased size of ventricles, could be a sing of shunt dysfunction. That is why, it is necessary to compare your previous CT scan finding with the last one.
The dizziness could also be related to other causes : an inner ear disorder, chronic degeneration of the cervical spine, etc..
For this reason, it is necessary consulting with a neurologist for a physical exam and discuss on the above issues.
Best wishes!
