Hi Dr. Lupo..This is the results from my Nuclear Thyroid Scan on 12/09/10..I had a NuclearNuclear ventriculographyMedicine Tyroid Scan on 12/09/10 here are the notes and impression. Study perfomed with oral ingestion of 283 microcuries iodineIodine strong (lugols)-123 at 9:43 am on 12/09/10 with imaging and uptake at 6 hours, uptake at 24 horus. Uptake is 18% at 6 hours which is in the normal range; 24-hour uptake is 25.7%. Imaging,however, shows hot nodule centrally in the rightRight step prenatal vitaminslobe of the thyroid with suppression of the activity in the entire left lobe. There is a hypoechoic area of a photopenic area centrally in the left lobe that could represent a cold nodule. Correlation to the u/s performed 11/18/10 shows a dominant nodule centrally in the rightRight step prenatal vitaminslobe measuring 1.6x1.5 cm. This corresponds to the hot nodule seen on nuclearNuclear ventriculographymedicine scan. In left lobe there is centrally a complexComplex a
Complex b
Complex b-100cystic lesion, 1.0 x .98 cm which corresponds to the photopenic area seen on the nuclear scan.
Impression: Nodule on the right is hot, i.e., shows increased uptake and corresponds to the solid nodule centrally in the right lobe on u/s. The left lobe is diffusely suppressed and there is no activity seen centrally corresponding to the complex cystic lesion in the mid left lobe of the thyroid. Hot nodules are typically benigh. The cold nodule is felt to represent a complex cystic lesion in the left lobe. Hyperfunctioning right nodule is suppressing the activity in the remainder of the left lobe of the thyroid.
I would greatly appreciate any comments to help me to decipher this information. I am being referred to an endocrinologist, but wanted to understand what's going on in the mean time. Thanks
The scan will tell you if the nodules are producing extra thyroid hormone leading to the slightly low TSH. If the right 2.9cm nodule is not definitively "hot" (over-functioning) then it should undergo FNA biopsy. TSI blood test to test for Graves' may also help in the evaluation of the low TSH>
Update to questions previously posted. Got my results from dr as follows:
Thyroid gland is examined with u/s. The right lobe measures 4.6x2x2 cm. The left lobe measures 4.8x1.6x1.5 cm. The isthmus is 4.8 mm. There are areas increased and decreased echogenicity throughout the right and left lobes. Several nodes are solid. Some are cystic. This is compatible with a goiter. No other findings demonstrated. complex echogenic pattern suggests the possibility of thyroid adenoma in the right lobe measuring 2.9x2 cm in size.
