I was recently sent to my family physician by my chiropractor who had taken some x-rays of my neck area which showed some abnormalities. My family physician sent me for an ultrasound and here are the results.
FINDINGS: The right thyroid lobe measures 4.7 x 1.5 x 1.7 centimeters. Within the mid portion of the right thyroid lobe, there is a hyperechoic foci with significant shadowing. This foci measures approximately 2 centimeters. No appreciable blood flow is seen in this area, however, the right thyroid lobe does show normal blood flow. The right thyroid lobe shows no other focal abnormality. The left lobe of the thyroid measures 3.5 x 1.0 x 1.0 centimeters and shows no focal abnormality with normal blood flow. The isthmus is normal.
IMPRESSION: Lesion in the right thyroid lobe appears to be calcified. There is shadowing posterior so the remainder of the lesion cannot be visualized. Suggest further evaluation with CT to evaluate this area for soft tissue nodule.
My questions are:
Why are the right and left lobes such different sizes?
What is a hyperechoic foci with shadowing and is the shadowing a good or bad thing?
Is 2 centimeters small, medium or large for a nodule or cyst on the thyroid?
Is no blood flow in that area of the thyroid a good thing? (I have read about hot and cold nodules but donít understand them)
What does it mean that the lesion on the right thyroid lobe appears to be calcified? (I did a search on the internet of thyroid calcifications and most of the sites had to do with cancer or carcinomas!!)
What is CT?
Should I request a fine needle biopsy to tell if it is cancerous?
Thank you in advance for any answers to my many questions and any opinions anybody may have.
