can you please help me interpret my thyroid ultrasound and scan Thanks.

[cindyduque03]

I have an enlarges left lobe.ultrasound findings states a prominent-sized left thyroid lobe with a solid heterogeneous mass. Normal right thyroid lobe.

Then my Thyroid scan states:
Technical report:
The patient was injected intravenously with 370 MBq (10 mCi) Tc99m pertechnetate. Static images of the anterior nesk were obtained in anterior and anterior oblique views 20 minutes after injection.

Imaging Report:
Tc99m thyroid imaging shows a normal sized right lobe measuring 4.7cm x 2.2cm. There is adequate and fairly uniform uptake of radionuclide with no focal defects noted.

The left lobe is slightly enlarged, measuring 4.5cm x 2.6cm  There is a well circumscribed photon-deficient defect accupying the lateral two-thirds, consistent with a hypofunctioning nodule.

Conclusion:
Slightly enlarged left lobe with a hypofunctioning nodule. Normal sized right lobe with no focal defect.

May I ask if I need to take a FNOB?

Thanks, Cindy

The radioactive scan was not really necessary if TSH is normal.
The nodule must be biopsied under doppler ultrasound to get sample from the solid portion of the nodule.

Hi Cindy,  Welcome to the forum!

It's my understanding that nodules that size are biopsied (I had a 3.5cm nodule and had a fine needle biopsy, which was painless and quick), although dependant on blood tests or other factors (I don't understand all of the findings you've copied above) so I'm not sure what your Doctors might advise.  Hopefully someone else with chime in soon.
