Working diagnosis: It depends on the location of the cyst, the extent of the chiari malformation on mri, what other symptoms you might have (difficulty swallowing, arm/legs symptoms, reflex changes). You might need an evaluation by an ear-nose-throat surgeon to see if there is a problem with the hearing and balance nerves. It becomes about choosing the most likely explanation after all the info are available.

Cyst Location: Unless the arachnoid cyst is in the area called your posterior fossa , the back of your skull area, the dizziness would more likely be related to a chiari. The tinnitus should be assessed by ENT with hearing test. The nausea if it is exertional may be a sign of vertigo or due to the chiari if associated with a headache. I agree you need some workup to tease things out.

Are you sure?: Did your neurosurgeon or neurologist diagnose the arachnoid cyst as the cause of your dizziness and tinnitus? If not, you may want their opinion as to whether this is really the cause of your symptoms.

work closely with your neurosurgeon about your Chiari I malformation. If you are having seizure, drops attack, loss of conciouness, respiratory problems, severe headaches, neck pain then surgery would be the best alternative.
