Summary
Medullary thyroid carcinoma (MTC) recurrence detection can be challenging with standard imaging. Whole body octreotide scintigraphy shows promise for identifying metastatic MTC when conventional methods fail.
Area of Science:
- Endocrinology
- Nuclear Medicine
- Oncology
Background:
- Medullary thyroid carcinoma (MTC) originates from parafollicular cells and is characterized by calcitonin and CEA secretion.
- Total thyroidectomy is the standard treatment, but recurrence detection remains a clinical challenge.
Observation:
- Conventional imaging (CT, MRI, U/S) often fails to detect metastatic MTC, even with elevated tumor markers.
- A case of recurrent MTC in a 40-year-old woman with persistently high calcitonin and CEA levels is presented.
Findings:
- Whole body octreotide scintigraphy was utilized to evaluate and detect the source of calcitonin and CEA secretion.
- This imaging modality was effective in identifying metastatic disease that was not apparent on conventional radiographic examinations.
Implications:
- Octreotide scintigraphy may serve as a valuable tool for detecting recurrent or metastatic medullary thyroid carcinoma.
- This technique can aid in guiding treatment decisions and monitoring disease progression in MTC patients.

Hyperthyroidism 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...
Graves 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...
Hyperthyroidism 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...
