what does all this mean

[linda0327]

I am a 45 year old female with thyroid nodules.  I currently had a ultrasound of my thyroid and here are the findings:
FINDINGS:  The right lobe of the thyroid is enlarged measuring 6.1x2.1x1.9cm.  It harbors two nodules.  One extends from the lower to the midpole and measures 2.4x1.4x1.5cm.  A second one at midpole measures 0.8x0.5x0.9cm.  Both are relatively well-defined and boh are very vascular.  The left lobe of the thyroid is normal in size measuring 3.2x1.1x1.8cm.  It is of normal echotexture.  The isthmjs measures 0.3cm.
IMPRESSION:  Right side hypervascular nodules, as described.
I have had blood work and my T4 level was 0.4 and my TSH was 0.56.  It was mentioned that I have something called Hashimoto Thyroidism.
I see an Endo on 20 May 2009 but I would like to know what all this means for me and I also heard that hypervascular means it could be cancerous??

I woud ask for an FNA biopsy...that way you might get a better idea on whether or not it is cancerous.

I can explain what Hashimoto's Thyroiditis is, and what TSH is,  Hashimoto's Disease as it is called, is an auto-immune disease, so your immune system is made of of T Cells, which fight bacteria etc in your body, in this case they do not recognize your thyroid gland and attack it, causing it to slow down or stop producing hormones and secreting them into your system, meanwhile your pituitary gland keeps sending a signal to your thyroid to secrete hormones (This signal is your TSH) via TSH, When your TSH is high, you are considered Hypo (Underactive) when your TSH is low you are considered Hyper (overactive) Now you can still have an underactive thyroid without having Hashi's The TSH only tells part of the story, its also important to know the Free T3 and T4 Labs, The normal range for TSH is supposed to be .3 to 3.0  Most Hashi's are in the higher TSH range (Mine was 6.0) unless you are swinging back and forth. If you have more questions please re post, some one will always try to help. Good Luck FTB4
