Summary
Metastatic papillary thyroid carcinoma (PTC) rarely causes ocular metastases. This case highlights choroidal metastasis in a patient treated for advanced PTC, presenting with vision loss.
Area of Science:
- Ophthalmology
- Oncology
- Endocrinology
Background:
- Ocular metastases from thyroid cancer are rare, with orbital involvement more common than uveal or choroidal.
- Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer.
Observation:
- A 56-year-old male with metastatic PTC underwent thyroidectomy and radioactive iodine therapy.
- Post-treatment whole-body iodine-131 scintigraphy revealed orbital activity.
- The patient experienced sudden vision decline in his right eye.
Findings:
- The patient was diagnosed with uveal (choroidal) metastases originating from PTC.
- This represents an uncommon presentation of metastatic thyroid cancer.
Implications:
- This case underscores the importance of considering ocular metastasis in patients with advanced PTC, even with initial orbital findings.
- Early detection and management of choroidal metastases are crucial for preserving vision.

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...
02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

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...
01:28Graves' 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...
