Summary
Thyroid cancer rarely spreads to the brain. This case highlights a rare instance of thyroid cancer metastasizing to the choroid plexus, suggesting a potential "seed-and-soil" interaction.
Area of Science:
- Neuro-oncology
- Endocrinology
- Radiology
Background:
- Intracranial metastasis from thyroid cancer is uncommon.
- Choroid plexus metastasis is a rare form of brain metastasis.
Observation:
- A 74-year-old woman presented with a large intracranial mass.
- Imaging revealed a thyroid nodule, lung nodules, bone metastasis, and a hypervascular brain lesion.
- Biopsy confirmed choroid plexus metastasis from thyroid carcinoma.
Findings:
- Thyroid cancer metastasis to the choroid plexus is rare but potentially overrepresented.
- This case adds to the limited literature on choroid plexus metastases.
Implications:
- The findings suggest a possible "seed-and-soil" relationship between thyroid cancer and the choroid plexus.
- Further research may elucidate mechanisms of this specific metastasis pattern.

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...

01:24Graves Disease II: Pathophysiology
59
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,...

01:28Graves' Disease I: Introduction
52
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...

01:25Hyperthyroidism I: Introduction
64
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...
