I just had ultrasound of my thyroid. I was wanting explanation of the report. I had a right thyroidectomy in 2004. The report says left lobe is normal. There is no normal thyroid tissue seen on right side. There is a tiny hypoechoic nodule in isthmus.

I just had ultrasound of my thyroid.  I was wanting explanation of the report.  I had a right thyroidectomy in 2004.  The report says left lobe is normal. There is no normal thyroid tissue seen on right side.  There is a tiny hypoechoic nodule in isthmus.

Easy: The thyroid has 3 parts. Right lobe, Left lobe and the connection between them, the Isthmus. Right side is gone, consistent with your surgery. Left side has no abnormalities seen by the ultrasound. The isthmus has a tiny nodule seen that is hypoechoic. US uses sound echos. Hypo means that it is less dense than surrounding tissue - likely fluid filled = cyst or black spot on the image. ...Read more

Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

Total thyroidectomy was NOT cancer. 3 years later ultra sound now says 6mm hypoechoic nodule may be residual thyroid vs benign appearing lymph node.

I've had total thyroidectomy & neck dissection & 2 rai treatments, ultrasound found tissue in thyroid bed, what does this mean?

I've had total thyroidectomy & neck dissection & 2 rai treatments, ultrasound found tissue in thyroid bed, what does this mean?

Uncertain: The only way to tell what the tissue in the thyroid bed is would be to do a needle biopsy. There could be scar tissue. There could be recurrent tumor. If the thyroid tumor picked up rai then a nuclear scan could show if there is recurrent tumor corresponding to the ultrasound findings. Talk with your oncologist. ...Read more

What does a hypoechoic non vascular round shaped nodule 7mm on thyroid bed. Post thyroidectomy. Meaning?

What does a hypoechoic non vascular  round shaped nodule 7mm on thyroid bed. Post thyroidectomy. Meaning?

Not entirely clear: This means there is a "nodule" or lymph node in the area where your surgery was. If the surgeon performed a partial lobectomy, then there could be some thyroid left there and also a nodule. It could be a lymph node that was outside of where the thyroid was. Also, in reality if the surgeon did remove the entire lobe, it could be remnant scar that is being interpreted as such. Speak with surgeon. ...Read more

My thyroid us report. Right thyroidectomy. Hypoechoic nodule in isthmus. .8 x .8 x 1.8 hypoechoic focus in right thyroid bed. No normal tissue in r?

My thyroid us report.  Right thyroidectomy. Hypoechoic nodule in isthmus.  .8 x .8 x 1.8 hypoechoic focus in right thyroid bed.  No normal tissue in r?

Thyroid ultrasound: By reporting "Right thyroidectomy" it is generally understood that the right thyroid lobe is surgically absent or has been removed. The .8x.8x1.8 hypoechoic focus in the right thyroid bed would suggest that there is something in the soft tissues behind where the thyroid was removed that is showing up. This could be a parathyroid gland, lymph node or something else. Get back with your doctor. ...Read more

I had total thyroidectomy. Hypodense nodule right thyroid bed 11mm by 9mm. Significance uncertain. Nonspecific lymph nodes. Could this be cancerous?

I had total thyroidectomy.  Hypodense nodule right thyroid bed 11mm by 9mm. Significance uncertain.  Nonspecific lymph nodes. Could this be cancerous?

Possibly: The total thyroidectomy was performed for a lesion in the thyroid that was not a goiter. That signifies that the lesion removed by the procedure had a potential for malignancy. Frozen section usually performed would inform surgeon of pathology and as such if Ca, a lymph node dissection would have been performed. If no Ca then any lesion in the bed is benign but should be followed. ...Read more

Partial thyroidectomy in 2006 for nodule, result was benign. Been on 100mcg Synthroid (thyroxine) but a new small nodule has appeared. Had ultrasound and told to not worry and come back in 1 yr. Do you agree?

Partial thyroidectomy in 2006 for nodule, result was benign.  Been on 100mcg Synthroid (thyroxine) but a new small nodule has appeared.  Had ultrasound and told to not worry and come back in 1 yr.  Do you agree?

Yes: Nodules are common in the thyroid. As long as you have thyroid tissues, there is always a chance of a new nodule popping up. If the past surgery was benign, and the new nodule is small, you can follow it with regular ultrasound and act on it (biopsy) only if there are significant changes on the ultrasound. ...Read more

Have 3.4 nodule in thyroid. If thyroidectomy, i'm afraid of weight gain. I am reading stories people gain weight and hormone hard to regulate help ?

Not to worry: If you have a thyroidectomy, they will give you thyroid replacement, and when adjusted properly, your thyroid level will be normal, and it will have no impact on weight. It is not hard to regulate. Has the thyroid nodule been biopsied? You may want to see an endocrinologist. ...Read more
