Other reasons for a widening of the IAC (Inner Auditory Canal)

[saritarita]

Hi,

 I got a CT Scan the other day to exclude acoustic Neuroma. It came back saying I had "widening of the IAC" and the couldn't rule it out and recommended an MRI. they didn't mention n if they could or couldn't see an actual AN. Is there any other reason apart from AN that this could happen? My symptoms aren't a severe as a lot of peoples on this forum: constant tinnitus in ear but only bothers me at night and vague wobbly feeling, specay feeling and a bit unsteady. Also have cracking/popping neck and headaches on the opposite side but I'm guessing these aren't related.

Thanks!

Hi Sritarita - and welcome to the ANA discussion forums.

Although we're not doctors and can't offer medical advice, your question is valid. An observed widening of the internal auditory canal (via CT scan) is a common occurrence in the presence of acoustic neuromas - but does not necessarily indicate an acoustic neuroma.  The widening could be caused by other issues but only an MRI - with contrast - will give you the answer you're looking for.

Thanks Jim, off to the docs again tomorrow to request an MRI with contrast-the hospital haven't triaged my referral yet so going to pay for it. Hopefully won't need to be back here!

Hi all,

 Well had the MRI and I don't have an AN so the answer is yes there are other reasons-not sure what or whether its really relevant now. Will head back to gp re the dizziness & tinitus.

Good luck everyone who is waiting.

Thanks for letting us know the results.  Very glad it is not an AN.  Hope you have answers and treatment soon for your bothersome symptoms!

You can still keep coming back here for reassurance anytime!
