Toxic Thyroid Adenoma


Presentation

  • Thyrotoxicosis as the first presenting illness in acromegaly is particularly uncommon, as described in this patient who had both acromegaly and a toxic thyroid adenoma.[ncbi.nlm.nih.gov]
  • The information presented here is intended to aid them in making an informed choice.[ncbi.nlm.nih.gov]
  • These cases can present a diagnostic and therapeutic challenge to the treating physician as the patient may present with symptoms of either disease.[ajol.info]
  • Abstract Toxic thyroid adenoma presenting as hypokalemic periodic paralysis is extraordinarily rare. We describe a 26-year-old Japanese man who suffered from acute and painful muscle weakness of extremity in the morning.[ncbi.nlm.nih.gov]
  • Costs and effectiveness were examined at their present values. Discounting (3% per year), variations of major cost components, and every variable for which disagreements exist among studies or expert opinion were examined by sensitivity analyses.[ncbi.nlm.nih.gov]
Thyroid Nodule
  • Hyperfunctioning thyroid nodules in multinodular goiters recognize the same pathogenetic event (TSH receptor mutation) as toxic adenoma. Other mechanisms are implicated in the growth of nonfunctioning thyroid nodules coexistent in the same gland.[ncbi.nlm.nih.gov]
  • Disorder that often occurs due to the growth of a thyroid nodule is called toxic adenoma of the thyroid gland. Nodes thyroid gland secrete thyroid hormones, which create serious problems in the body.[cancer.vsebolezni.com]
  • Doctors call these “ thyroid nodules .” They may be solid or filled with fluid. What Causes Them? It’s not always clear why a person gets thyroid nodules. Several medical conditions can cause them to form.[webmd.com]
  • Approx. 5% of thyroid nodules are malignant, with papillary carcinoma being the most common. Thyroid hormone assay is the best initial test in the evaluation of thyroid nodules.[amboss.com]
  • Can Iodine Shrink Thyroid Nodules? There is some evidence which shows that iodine can shrink thyroid nodules. Dr.[naturalendocrinesolutions.com]

  • Not all nodules are toxic, and some cases may present as euthyroid. Radiotracer uptake is focal, unlike in Graves disease. 2 articles feature images from this case[radiopaedia.org]
  • Usually, patients with TH are biochemically euthyroid and clinically asymptomatic [9]. Most of the cases of TH are diagnosed when the patients present a lesion in the functioning lobe.[cureus.com]
  • Seventy-seven percent were euthyroid by 2 months, 91% by 6 months, and 93% by 1 year. Only 3 patients did not respond to a single dose of 131 I, but all responded to multiple doses.[annals.org]
