Milt,
I started out with similar loss of hearing, tho I did not have a spinal tumor like you. When I went to my ENT, his first reaction was to put me on a course of steroids. I had gone to the ENT because my husband was having the same symptoms . . . the ENT said it was likely we had a virus, but thought the steroids were the best first route. My husband's hearing came back after the steroids. Mine did not. He was eventually diagnosed with Meniere's and is on diuretics, blood pressure meds, and anti-histamines which together are keeping the symptoms minimal - he still has some tinnitus, but no dizziness.
When the steroids didn't work for me, the ENT sent me for blood tests and threw in the MRI because there was a small chance (he said) that it might be an AN.
Turned out I had an AN AND a meningioma. He was stunned. It took a couple of months and several specialists, but I got a diagnosis of NF2. He had never seen a case of NF2 before, and didn't know that's what I had, but at least when he saw the second tumor he knew enough to refer me to a neurotologist - who knew about NF2, but knew that he didn't know enough about it (AND that with only 2 tumors I was an atypical NF2 patient) and referred me to the NF2 clinic at Mass General.
All by way of saying, your spinal tumor may or may not be related to your hearing loss - but if I were you I'd try the Meniere's regimen for a month and then if your hearing has not improved I'd push really hard to get an MRI. ANs are usually slow-growing - a month is not a long time (tho it may feel like it!!) If the MRI shows even one brain tumor, I'd then push for a referral to an NF2 specialist. NF2 tumors are not treated the same way as regular ANs. It's unusual I think for spinal tumors to show up first in NF2 patients, but there are always unusual cases!
Keep us posted!
