Thyroid ultrasound showed heterogenous  echogenicity hypervascular thyroid. Thyroid labs normal. Any thoughts on what this is?

See endocrinologist: It is unclear why these studies are being done, especially if thyroid blood tests are normal. You should see an endocrinologist to have him/her interpret these tests. That ultrasound is consistent with hashimotos thyroiditis. ...Read more

Thyroid Nuclear Scan (Definition)

This scan involves taking orally a small dose of radioactive iodine. The iodine is taken up by the thyroid and produces an image. "cold" areas are places with no iodine uptake. "hot" areas have a lot of uptake. The radiologist also calculates the percent uptake of the iodine. This test is important in the diagnosis of hyperthyoidism, thyroid cancer, and follow ...Read more

Test results are multinodular goiter so radionuclide thyroid scan?

Test results are multinodular goiter so radionuclide thyroid scan?

Need more info: Not sure what you mean by "test results" but u cannot know that u have multinodular goiter from a blood test. A thyroid ultrasound can give u this diagnosis in which case u will need a blood test called TSH to know what to do next. No thyroid scan needed unless the TSH is low. Thyroid ultrasound vs. Biopsy might be needed depends on the size and characteristics of the nodules but need more info. ...Read more

Thyroid Ultrasound heterogenous thyroid parynchema with hypervascularity. Blood test normal tsh t4 t3 (liothyronine) etc but >1300 TPo antibodies?have Hypo symptoms

Elevated: TPO levels are associated with autoimmune thryroid disease/thryoiditis, for example Hashimoto disease. The thyroid US findings are also consistent with thyroiditis. Talk to your doc about next steps. ...Read more

Tsh level 5.58, no symptoms, u/s found 1cm subtle hypoechoic nodule w/increased peripheral vascularity. Pcp ordered rai uptake scan before fna. Why?

Tsh level 5.58, no symptoms, u/s found 1cm subtle hypoechoic nodule w/increased peripheral vascularity.  Pcp ordered rai uptake scan before fna.  Why?

I have no idea: Hi. It's not a hyperactive nodule...we know that from the TSH. I'd go straight to an FNA. The scan will show a "cold" nodule, which we already know it is, and will not help differentiate benign from cancer. FNA cytology (hopefully with gene testing) is all you need at this point. Good luck. ...Read more

Low TSH Borderline low T4 normal t3 (liothyronine). Thyroid uptake scan..low uptake noted w\o nodules. Radiologist said HYPOTHYROIDISM?! All other possible test norm

Low TSH Borderline low T4 normal t3 (liothyronine). Thyroid uptake scan..low uptake noted w\o nodules. Radiologist said HYPOTHYROIDISM?! All other possible test norm

Need follow-up: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, there is inconsistency in your results. Both TSH and T4 being low does not add up. You may need to repeat the lab tests, not necessarily the scan, in about 6 months to see what direction these results are going in. ...Read more

Thyroid sono showed heterogeneous gland with multinodular goiter(positive hashimoto's diagnosis;on synthroid)-follow up sono when?

10---15 days: You have autoimmune hypothyroidism and need to to be seen by an endocrinologist , who want to be sure cold or hot nodules and act accordingly and adjust synthroid (thyroxine). ...Read more

Thyroid swelling. Ultrasound heterogenous thyroid parynchema with hypervascularity. Blood test-normal tsh t4 t3 (liothyronine) etc but >1300 TPo antibodies?

Thyroid swelling. Ultrasound heterogenous thyroid parynchema with hypervascularity. Blood test-normal tsh t4 t3 (liothyronine) etc but >1300 TPo antibodies?

Hard to say: Ive yet to have anyone NOT have elevated TPo but I havent sent many. The standard answer would be that it likley is GRAVES disease starting but if there arent a lot of symptoms and the labs are normal you wouldnt give treatment. Retesting if symptoms and at about every 3 months. ...Read more

Single hot 1 CM nodule on thyroid scan with normal thyroid blood panels & uptake. Chances of malignancy?

Single hot 1 CM nodule on thyroid scan with normal thyroid blood panels & uptake.  Chances of malignancy?

Not likely: "hot" nodules are rarely cancer and most often represent benign follicular adenomas. These are also known as "autonomous" nodules because they make thyroid hormone but don't respond to the body's normal signals telling them when to stop making the hormone. The vast majority of thyroid cancer nodules are "cold" on a thyroid scan. ...Read more

Thyroid gland hyper functioning nodule right lobe multi nodular goiter. What does this all mean?

Thyroid gland hyper functioning nodule right lobe multi nodular goiter. What does this all mean?

Multinodular goiter: Hi. Your hyper-functioning nodule is producing thyroid hormone without pituitary regulation. Since you have multiple nodules, chances are they're all overproducing thyroid hormone (aka "hot" nodules). Your radio-iodine scan will tell. Any "cold" nodule of certain size will need to be evaluated to make sure it's not cancer (you may not have any cold nodules). Treatment with 131-Iodine is easy. ...Read more

Thyroid U/S showed L thyroid gland heterogeneous hypoechoic nodule w/ mind internal vascularity. what does all this mean? FNA recommended.

Means abnormal test: Ultrasound is a commonly used test for detection of Throid nodules which are quite common. So when the ultrasound shows a Thyroid nodule, it needs to be monitored and often a Biopsy is required to find out if the nodule is benign or cancerous. FNA is one such technique for obtaining a biopsy for making a diagnosis. ...Read more

Thyroid ultrasound show mild diffused parenchymal hyper vasuclarity.3mm hyperechoic nodule in the lateral aspect in the left lobe thyroid normal > tsh?

Possibly thyroiditis: Hypervascularity is a typical finding in people with underlying autoimmune thyroiditis (hashimoto's or graves disease). The 3 mm nodule is likely of no significance and can be watched. You need to know your TSH level. Getting thyroid antibodies (thyroid peroxidase, thyroglobulin antibodies) would be helpful in making a diagnosis. ...Read more

Thyroid ultrasound shows heterogenous hypervascular echogenicity. No nodules. Thyroid labs were normal. Any ideas on what this is?

What thyoid labs?: There are many thyroid labs and most docs do not check enough of them? This ultrasound is consistent with grave's disease and thyroiditis. With grave's standard thyroid tests would usually be abnormal but might look ok with thyroiditis. Please make sure anti-thyroid antibodies (anti-tpo and anti-thyroglobulin) have been checked, as well as free t3 (liothyronine) and reverse t3 (liothyronine). ...Read more

Thyroid nodule of the right lobe. Fna indicated follicular lesion-also hypothyroid, family history of malignant thyroid nodules. Options?

Surgery or...: A repeat biopsy combined with an afirma assay test may give you somewhat better guidance, but with your history and risk factors, surgery may be the best option. By the way, why are you taking generic T4 an Armour Thyroid together? There is no way to monitor the dosage properly as the lab tests will be unreliable. Brand name T4 is better, safer and more reliable. ...Read more

Nuclear Scans (Definition)

From a cardiac perspective nuclear scans are performed with either exercise or medications to examine the blood flow in the heart. Before and at peak exercise the patient is given a radio tracer which travels in the blood to the heart. Pictures are take before and after exercise and compared to evaluate for any blockages in the ...Read more
