Presentation
Patient presented with weight loss, generalized fatigue and diarrhea. Bloods showed low TSH with raised T3 and T4.
Patient Data
The thyroid gland is normal in size and entirely suprasternal (compared to the SSN [suprasternal notch] marker).
There is homogeneous uptake within both lobes of the thyroid gland. This uptake is homogenously increased when compared to the normal salivary glands.
The patient has a neck-to-thigh ratio of 17.6, which quantitatively supports the finding of increased uptake.
Case Discussion
Given the clinical history of hyperthyroidism, the Tc-99m pertechnetate thyroid scan findings are consistent with Graves' disease.
Following this scan, the patient was diagnosed with Graves' disease and treated with carbimazole. At the 3-month follow-up with the endocrinologist, the patient reported improved symptoms and showed improvement in TSH.
