Hey Cobra,
Glad you got your MRI done. Unless your doctor actually has his/her own MRI, you probably had it done at a radiology center, right? If that's the case, you can call them directly - they will provide you with a copy of the radiologist's report. This is a just a one-page summary of your MRI, but it will indicate if they found an AN. This is exactly what I did, and as I recall, I was able to pick up my report the next day. Although I couldn't actually see the pictures until I met with my doc, I at least knew it was an AN, and walked into that doctor's appointment both prepared and informed.
It was actually sort of funny - my neurotologist was putting on his best 'I have bad news for you' act as soon as he walked in the door. Very concerned look, serious expression, MRI film tucked beneath one arm. I think it threw him quite a bit when I started talking treatment options for him, but it also made for a much more pleasant discussion. He didn't have to calm me down about my brain tumor, so we were able to talk treatment right away. Very helpful.
So, I highly recommend calling the radiology office to see if you can pick up your report. One caveat: if you do have AN, take the measurement on the report with a grain of salt. Radiologists may only see a handful of these in a lifetime, and may not know how to properly measure them. My report read 'Probably 2.5 cm Acoustic Neuroma'. A 2.5 cm AN is right on the medium/large boundary, and I began my treatment research based on that number. However, when I met with the neurotogolist, he did a second measurement, and it was actually over 3cm, which is definitely a 'large' tumor. Use the radiology report as a starting point, but wait for your doctor to do a second measurement. (My 3cm AN, it turns out, is pressing against my brainstem - not a good candidate for radiosurgery.)
Okay, I'm done - sorry for rambling on!
Hope all goes well - keep us posted!
