should thyroid nodule be rebiopsied?

[skooter63]

In 2004 a goiter was found on an incidental cspine mri.  I underwent an ultrasound that showed a 3.7x1.6x1.9cm solid nodule.  It was biopsied and it was non malignant.  Initially in 2004 I had one lab result that was t3 of 7.6pg/ml, t4 if 2.09ng/dl and a tsh of 0.305. Along with a nuclear medicine study in 2004 that indicated a multinodular goiter. As directed I have seen a endocrinologist once a year  and all subsequent thyroid levels have been normal.  Recently  April 2010, I was sent for another thyroid ultrasound by my primary doctor because she felt like it was time to be imaged again.  I had visited her complaining of tiredness that had been lingering.  I thought I might have mononucleosis.  To make a long story short, the ultrasound noted a heterogenous, predominantly solid appearing mass measuring 2.9x1.3x1.4cm with numerous coarse and microcalcifications within the lesion.  No adenopathy seen in jugular chain or supraclavicular region.  The radiologist recommended a us guided fine needle biopsy.  When I saw my endocrinologist he said that he did not think I needed another biopsy because he had never seen these type lesions turn out to be cancer.  My question is since microcalcifications were seen on the new ultrasound, wouldn't a new biopsy be prudent?  I understand that most turn out normal.  I would appreciate your advice. thanks

Thanks for the information from you both.  MANmom, I hope you have recovered fully.  God Bless!

They thought mine was degenerating, my own brother (a radiologist) said that's what it looked like, it was all cancer.  They really can't tell until they take it out.  Get the biopsy, you may or may not get an answer, but don't ignore it.

The nodule is likely undergoing degeneration and it shrunk inthe size. However, based upon  the finding of microcalcifications it can be a good idea to do biopsy again.
