interpreting thyroid sonogram and lab reports

Postby kmp » Fri Sep 11, 2009 7:36 am

Some lab results before thyroid sonogram. Nov. 08 TSH normal, Sept. 09 TSH IRMA Turbo 7.857 (H), Sept. 09 FT4 12.625 (wnl)
Sonogram report 2.1 x 2.2 x 2.0 cm complex mass with distinct solid component and minimal rim calcification in the superior-middle aspect of the left thyroid lobe. Normal right thyroid lobe.
Not yet on any thyroid meds. What should be next step? Is this likely cancer? Will see Endocrinologist next week, but anxious to have more information when I go to see him. Thank you.

The ultrasonic appearance of a thyroid nodule does not reliably differentiate a benign thyroid lesion and cancer.

However, there are some ultrasonographic signs that are thought to indicate increased risk of cancer--

1.Central intra-nodular vascularity

2. Incomplete/absent halo

3. Hypoechoic nodules

4. Irregular margins

5. Microcalcifications

6. Documented enlargement of a nodule

7. predominantly solid composition

One must remember that these are only certain guidelines (not universally accepted)

Certainly the next step most would recommend in your case would be a FNAC(Fine Needle Aspiration Cytology) of the mass(whatever the result of Thyroid function tests).
best wishes!
