Hi Debbie and congrats for the 6mos mark...... what I can share is this... head MRI's have a total margin of error of +/-2mm, so overall, you are in that range. Different radiologists and drs read and measure differently. I can tell you that my neuro-onc, who's on my CK team, reads and measures my AN differently than my CK radio-onc.... go figure? I usually take their average and determine it from there. As you can see in my sig line, I'm running about 2mm +/- in my AN measurements over time with some minimal shrinkage, so for me, I've come to terms with it. My hope is that there is no swelling going on and that you all have stunted its growth (ultimate goal of radio-treatment for AN's).
We didn't see any darkening of my AN for quite a while in my films. One wise person on this site reminded me that at the time the films/MRI is done, you have to "snap the camera" at the right time to see it. As you are only 6 mos post-CK, it may be more prevelent in films down the road.
The good news is that you are now a good distance post treatment.. and hoping the 2mm is nothing to worry about... and that you are hanging in there as best as you can.... and you got all of us cheering you on.
Hang in there! Onward and upward to wellness.
