MRI results

The results are in.
They do not surprise me.
The acoustic neuroma shows up as slightly larger on recent imaging.

Studies report:

Acoustic neuromas sometimes increase in size temporarily as a reaction to the Gamma Knife treatment. This is actually a favorable sign indicating a brisk response. Such swelling usually is most obvious between 6 and 18 months after the procedure. It should not be confused with increase due to lack of response in which case the tumor size will not return to the baseline but continue to increase. A definite assessment should be made two years after the treatment: was the swelling merely temporary or did the tumor fail to respond to the treatment?

This increase likely accounts for the increase in the spinning sensations and tinnitus.  I am glad there is so much information available online.  I have read much that helps dispel fear.

The neurosurgeon wants me to have my next MRI in one year.
In one year I expect to be on the mission field in Malawi.
We will have different insurance coverage.
My doctor here can not requisition treatment overseas.
It may well be possible to have the scan done in Africa and sent home on a disc.
but think I will request that the MRI be done at the seven month mark
if we are indeed leaving Canada in August
then re imaging can be done again two years later
when we return home on furlough.
I am leaving this in the Lord's hand for the moment
but will send an email to the neuro nurse in a few days.
Having the test completed on home soil
would eliminate stress and worry in our future planning.

One thing I am certain of
God already knows.
He Is already living in my future.
