Christy .....
In the midst of my husband's emergency surgery, our power outage for a week, etc. I missed your posts on your vestibular function concerns so I am sending you a PM regarding that.
All I will say here is ..... yes, even experts can disagree on whether what they see on an MRI post-op is residual tumor, regrowth, or "surgical changes." My first AN surgery was in February, 2008, via retrosigmoid/suboccipital approach. My first MRI was ordered at six months post-op. Even on that first post-op MRI, there was an "area of enhancement" that my local radiologist felt could be residual tumor, but my surgeon said it was scar tissue. End of story ..... whatever it was, between February, 2010 and February, 2011 it grew 3 mm ..... measuring 1.3 cm by this time. Thus, I had a second surgery in May, 2011 via translabyrinthine approach and the only post-op MRI in November, 2011 showed no areas of enhancement!!
Please remember that each of us is unique so my story should in no way mean that you have the same situation. If it were me, I would certainly go for a third opinion regarding the meningitis, even though Dr. Slattery is tops in the field. UPMC in Pittsburgh gives free consultations from MRIs, as well as other facilities around the country. Are there not other tests to confirm or disprove meningitis?
Regarding the balance ..... we do know that if a vestibular nerve is not severed, but is mis-firing, it confuses the brain and it results in ongoing balance issues when the brain cannot shut off the mixed signals and adjust to only one good vestibular nerve functioning.
Remember, I am not a doctor ..... these are things I have gleaned from my own experience and research.
