Ok, I'm another one not sure what that muscle is, I could look it up in Gray's anatomy I guess.

First PET/CT scan after surgery and radiation, that big honkin muscle that runs vertically down the side of the neck glowed like it was radioactive. Oncologist said either healing process or residual cancer both will show up on a scan. Subsequent scans showed less and less, so it didn't show up at all on last scan, one year later. Guess it wasn't residual cancer.

If it's the whole muscle showing up, most likely healing from the surgery/rad. See the surgeon for professonal peace of mind, my experience anecdotal
