Summary
This case study details a 68-year-old woman initially diagnosed with Graves' disease and orbitopathy, who later developed hyperthyroidism due to a functioning thyroid nodule. Successful treatment with iodine-131 (131I) therapy normalized her thyroid function.
Area of Science:
- Endocrinology
- Nuclear Medicine
- Thyroidology
Background:
- Graves' disease is an autoimmune disorder often associated with orbitopathy.
- Autonomously functioning thyroid nodules can cause hyperthyroidism.
- Distinguishing between Graves' disease and functioning nodules is crucial for effective management.
Observation:
- A 68-year-old woman with a history of Graves' disease and orbitopathy presented with recurrent hyperthyroidism.
- Thyroid imaging revealed a solitary, hyperfunctioning nodule in the right thyroid lobe.
- Fine needle aspiration biopsy showed no signs of malignancy.
Findings:
- The patient's hyperthyroidism was attributed to the autonomously functioning thyroid nodule, superimposed on underlying Graves' disease.
- Radioiodine (131I) therapy was administered for the functioning nodule.
- The patient achieved a stable euthyroid state for over one year post-treatment.
Implications:
- This case highlights the importance of considering autonomously functioning thyroid nodules in patients with Graves' disease and hyperthyroidism.
- Radioiodine therapy can be an effective treatment for such complex thyroid conditions.
- Accurate diagnosis and tailored treatment are essential for managing patients with coexisting thyroid disorders.

01:28Graves' Disease I: Introduction
Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence in...
01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
01:25Hyperthyroidism I: Introduction
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
01:27Goiter
Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...
01:23The Thyroid Gland
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...
