The thyroid pathology represented by these images is?

• A. Thyroiditis
• B. Thyroid carcinoma
• C. Multinodular goiter
• D. Graves disease

Answer: (D)

Graves disease is an autoimmune disorder that is the most common cause of hyperthyroidism. The imaging characteristics associated with Graves disease often include an enlarged thyroid gland (goiter) and increased uptake of radioactive iodine or technetium in the thyroid gland on scintigraphy, indicative of increased function. In Graves disease, the thyroid tissue is stimulated by thyroid-stimulating immunoglobulins, leading to hyperplasia of the follicular cells. This can manifest on imaging as diffuse enlargement of the thyroid with potentially a homogeneous distribution of uptake, distinguishing it from other thyroid conditions which may have different uptake patterns. The presence of any additional signs, such as infiltrative ophthalmopathy and dermopathy, can support the diagnosis of Graves disease as well. These features are vital in differentiating from other conditions such as thyroiditis, which typically shows decreased uptake, or thyroid carcinoma, which may present with solitary nodules or abnormal uptake patterns. Recognizing these imaging characteristics and correlating them with clinical findings is critical in diagnosing Graves disease and differentiating it from other thyroid pathologies.
