Multiple small nodules on ultrasound,
largest 1cm in diameter in the right lobe. ? cold.
Scan Appearance:
There is irregular tracer uptake seen throughout both lobes with
a prominent photopenic area in the mid pole of the right lobe.
Scan Findings:
Multinodular gland with a dominant cold nodule in the mid pole
of the right lobe.
Suppressed TSH. Symptoms of fatigue and
weight gain. Ultrasound demonstrates solid nodules in both lobes
of the thyroid.
Scan Appearance:
There is diffusely increased tracer uptake in the large nodule
in the left lobe (red arrow) and the smaller nodule in the upper
pole of the right lobe of the thyroid (blue arrow). The thyroid
elsewhere is not visible, which is consistent with suppression
of uptake. The thyroid to background uptake ratio is moderately
elevated measuring 18.8:1 (normal range 3 – 8:1).
Scan Findings:
Autonomously functioning nodules in both lobes of the thyroid.
A review by an endocrinologist with consideration of antithyroid
medications to achieve a euthyroid state is suggested. Treatment
with radioactive iodine may be required for long term control
of these toxic nodules.
Scan
Appearance:
There is diffusely increased tracer uptake throughout both lobes
of the thyroid which appears at the upper limits of normal in
size. The thyroid to background uptake ratio is markedly elevated
measuring 55.3 (normal range 3 – 8).
Scan Findings:
The scan appearances are typical of active Grave’s disease.
