Small hypodensities within the thyroid gland which would be better evaluated with thyroid ultrasound as indicated. This is directly from a recent CT scan that I had done. I have had Stage 0 melanoma and I am a little concerned as I believe it may have returned (blue mole on chin is now black). I am scheduled for an ultrasound in about a week in a half. Any advise would be greatly appreciated. Have a dermatologist appointment coming a couple of days before ultrasound.
