There are no silly questions .......
I am not a doctor, but to the best of my knowledge ANs grow from the cells covering the vestibular portion of the auditory nerve, as it leads from the brainstem to the cochlea (one on each side). This area is outside the cerebellum or cerebrum where other critical functions are found. See
http://www.waiting.com/brainanatomy.html for a better explanation. It is my understanding that the left cranial nerves (which include the auditory nerve ...... nerve VIII) control the left side. An injury such as a stroke that occurs within the cerebrum controls the opposite side.
My AN was on my left side, which is where my hearing loss is and where that surgery was done. My previous trigeminal neuralgia (nerve V) was on my right side, which is the side the surgery for that was done.
It seems incredible to me that a neurosurgeon's nurse does not know how MRIs work!?!?!
I would certainly ask some really hard questions from someone else in that office if you pursue this medical group. Can you ask someone to show you your actual MRI of your AN? Then you will know for sure which side it is on. Either your doctor or the imaging center should be able to do that.
Let us know what is going on.
