In either case, if surgery is selected as the treatment, a surgeon with expertise in thyroid surgery should be chosen to minimize the risk of complications. The key difference between Graves Disease and hyperthyroidism is that the Graves’ disease is a pathological condition while the hyperthyroidism is a functional abnormality which is a result of an ongoing pathological process. In hyperthyroidism, there is a high level of thyroid hormone in the blood plus a low level of TSH. Hyperthyroidism is the state of the increased level of free thyroxin hormones which can be due to various causes including the Graves disease. Radiotracer uptake is focal, unlike in Graves disease. Vidal-Trecan GM, Graves’ disease is one cause of hyperthyroidism. Outcome of radioiodine-131 therapy in hyperfunctioning thyroid nodules: a 20 years' retrospective study. Fine needle aspiration biopsy may be necessary for some of these nodules. Treatment of thyroid storm is summarized in eTable C. note: A score of 45 or greater is highly suggestive of thyroid storm, a score of 25 to 44 is suggestive of impending storm, and a score below 25 is unlikely to represent thyroid storm. Do not order multiple tests in the initial evaluation of a patient with suspected thyroid disease. The surgical management of goiter: Part II. This test uses radioactive iodine to show where the thyroid is functioning. et al.

In contrast with these three disorders, painless or transient (silent) thyroiditis causes a destruction of thyroid follicles via an autoimmune mechanism and a release of preformed thyroid hormones into the circulation.5 Its clinical presentation is the same as with other causes.
