Need evaluation: There are many possible causes for your current symptoms. Although the ct showed "small calcified densities in the thyroid", it still might not be the cause for your difficulty swallowing. The next step would be a thyroid u/s to see if these "densities" are in a nodule and to see how many nodules & how big they are. Get the ct result, sit down with your doc and discuss the next step of evaluation. ...Read more

What would cause a 4mm hypoechoic nodule in left lobe of thyroid gland, along with prominent bilateral cervical lymph nodes as found in a neck US?

Thyroid cyst: It sounds like you have a simple thyroid cyst and possiblt a couple of reactive nodes that may be within normal. Why did you have an ultrasound? 4mm cysts is not palpable.

Is a hypodense lesion on the thyroid cancerous? I had an angiogram and it found a hypodense lesion on the left lobe of my thyroid gland.

A 0.3 x 0.5 x 0.3 CM hypoechoic cystic nodule with punctate internal echo is noted in the lower pole of the right lobe of the thyroid gland.?

Small nodule: Often cystic thyroid nodules can have denser regions called "punctate foci". If the nodule is not cystic those can also be microcalcifications, a finding that increases the risk of thyroid cancer. The key though is that the nodule is very small and therefore requires monitoring only, no matter what its nature may be. ...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

In follicular adenoma of thyroid gland, after lobectomy, is ther resk for other remaining lobe to develop follicular carcenoma?

VERY LOW: In treating thyroid tumors the lesion present should be solitary and essentially cold on thyroid scan. At that time if surgery indicated should the lesion be relatively small and confined to one lobe it is possible to save the other lobe. Ca Dx is made when the adenoma shows evidence of follicular cells breaking the capsule. A second primary occurs in the other lobe in about 5% of patients ...Read more
