Probably not: Did you have thyroid cancer or just a goiter 10 years ago? If no cancer, then there is nothing to worry about. You probably had positive antibodies 10 years ago as well. If you did have thyroid cancer 10 years ago and the antibodies were negative and now positive, then it's time for an evaluation. ...Read more

Tissue (Definition)

The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more

Antibody is not: dependent on thyroid tissue. The body makes antibodies by different cells than the thyroid. The antibodies can persist even if no thyroid tissue is left. ...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 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

Residual thyroid: The surgeon cannot remove every last remnant of thyroid. This is why RAI is often given after thyroidectomy, to mop up any residual thyroid tissue-normal or cancerous. The US may just be detecting residual thyroid that the surgeon did not get. See your Endocrinologist. ...Read more

Had lump on thyroid biopsy came back ok. Another lump came up within 3 weeks now had partial thyroidectomy. What's the chance new lump is cancer?

Not high: Off course the risk for someone to develop cancer will depend on different things like your personal history, your family history, history of radiation the neck area, environmental exposure etc. Majority of the thyroid nodule is benign. The risk for thyroid nodule to become cancerous is only about 5-10%. Discuss further with your doctor. ...Read more

Is it possible recurrence of thyroid cancer if thyroglobulin came back positive but antibodies are decreasing? Had full thyroidectomy 2 years ago.

Recurrence: Rest assured. It is impossible to say you are cancer free, but that is likely. Here's why: the thyroglobulin level is unreliable because you have antibodies. The fact that the antibodies are decreasing can mean that thyroglobulin is decreasing. Antibodies can be a tumor marker surrogate. Continue to follow the antibody trend and get periodic neck ultrasounds. ...Read more

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

How does a thyroidectomy affect your thyroid levels?

Thyroidectomy: If they did a complete thyroidectomy, your thyroid levels should be low; you should become hypothyroid and need to be on levothyroxine. However, sometimes surgeons do not do a complete thyroidectomy, depending on why the surgery was done. If they did a non-complete resection, but then the thyroid gland is not normal (eg. Hashimoto's), then you may get hypo even though there is tissue left behind ...Read more
