• Thyroid Nodule

  Are you sure the patient has a thyroid nodule? Thyroid nodules are common and most often benign. However, 8-15% of all nodules can prove to be cancerous. There are ~50,000 new cases of thyroid cancer annually in the United States. [endocrinologyadvisor.com]

  Thyroid ultrasonography is recommended in all patients with suspected thyroid nodules and for the initial evaluation of thyroid nodules discovered through other modalities. [empendium.com]

• Inflammation

  Inflammation of the Thyroid Common causes of an inflamed thyroid include autoimmune thyroiditis (also called Hashimoto's thyroiditis), which occurs when the person's immune system attacks its own thyroid, causing swelling and inflammation. [ucsfhealth.org]

  Chronic inflammation of the thyroid. Hashimoto's disease, a thyroid disorder, can cause thyroid inflammation and result in enlarged nodules. This often is associated with hypothyroidism. Multinodular goiter. [mayoclinic.org]

  Inflammation of the thyroid gland ( thyroiditis ) can produce gland swelling. Some forms of thyroid inflammation are quite common, such as autoimmune thyroiditis and painless (postpartum) thyroiditis. [endocrinesurgery.ucsf.edu]

  CONSUMERS: Click here for the Consumer Version Simple nontoxic goiter, which may be diffuse or nodular, is noncancerous hypertrophy of the thyroid without hyperthyroidism, hypothyroidism, or inflammation. [merckmanuals.com]

  Cysts may be the result of an injury or inflammation, or may occur along with benign or cancerous growths. They may need to be drained or biopsied so that our endocrinologists can make a diagnosis. [nyulangone.org]

• Aspiration

  In some communities, it is not the endocrinologist who performs the fine needle aspiration biopsy. [healio.com]

  In contrast, 5-8% of thyroid nodule aspirates will demonstrate cytology positive for papillary carcinoma. Figure 2. Thyroid nodule fine needle aspiration (FNA) Approximately 20-25% of thyroid nodule aspirates will have indeterminate cytology. [endocrinologyadvisor.com]

  The evaluation of the patient with solitary thyroid nodule is generally straightforward and will typically include measurement of serum TSH to assess thyroid function and fine-needle aspiration biopsy of the nodule, with or without ultrasound (US) guidance [mayoclinic.pure.elsevier.com]

• Muscle Weakness

  Symptoms of this thyroid condition include muscle weakness, a rapid heartbeat, weight loss, irritability, vision problems, and infertility. Hyperthyroidism can be caused by thyroid nodules, or lumps on the thyroid gland. [diabetesandmetabolism.com]

  Hyperthyroidism can result in weight loss, muscle weakness, heat intolerance, and anxiousness or irritability. [mayoclinic.org]

  Autonomous hyperactivity is conferred by somatic mutations of the thyrotropin, or thyroid-stimulating hormone (TSH), receptor in 20-80% of toxic adenomas and some nodules of multinodular goiters. [1] Autonomously functioning nodules may become toxic in [emedicine.medscape.com]

If any changes occur, then further workup is indicated. Evidence-based answers from the Family Physicians Inquiries Network [mdedge.com]

[…] and pelvis (23%), however, such lesions in the long bones and skull are less common (6% each [4] Multiple bone site involvement at a given time is also quite frequent (40%), as seen in our patient. [7] Patients with metastatic disease need a complete workup [ijem.in]

Treatment and prognosis ----------------------------------------- Treatment of multinodular goitre may be pursued if the thyroid is hyperfunctioning, or if the goitre is causing local mass effect. [youtube.com]

Three of these 8 patients had 1 131 I treatment, 4 patients had 2 treatments, and 1 patient had 3 treatments. These patients did not want subsequent 131 I treatment and were given long-term antithyroid drug treatment. [jamanetwork.com]

In such instances, surgical treatment or radioactive iodine treatment (also known as radioiodine ) may be considered for a more permanent treatment of overactive thyroid. [yourhormones.info]

Treatment and prognosis ----------------------------------------- Treatment of multinodular goitre may be pursued if the thyroid is hyperfunctioning, or if the goitre is causing local mass effect. [youtube.com]

The type of cancer (PTC or FTC) was not a significant indicator of prognosis. [ijem.in]

Expectations (prognosis): The prognosis is good with treatment. A persistent goiter may become toxic, causing symptoms of excess thyroid hormones to develop. [uclahealth.org]

Other tests that may be done include: Serum thyroid hormone levels ( T3, T4 ) Serum TSH (thyroid stimulating hormone) Thyroid uptake and scan or radioactive iodine uptake Thyroid ultrasound Outlook (Prognosis) Toxic nodular goiter is mainly a disease [account.allinahealth.org]

Treatment depends on the underlying etiology and includes, e.g., surgery ( thyroidectomy ) for malignant and autonomous nodules, fine needle aspiration for thyroid cysts, and observation for small, benign nodules. [amboss.com]

The etiology of nontoxic MNG is multifactorial, with the important factors including, among others, iodine deficiency (initially manifesting as a simple goiter), genetic predisposition, goitrogens, exposure to ionizing radiation, and history of thyroiditis [empendium.com]

However, the true etiology of most nontoxic goiters in iodine-sufficient areas is unknown. Symptoms and Signs The patient may have a history of low iodine intake or overingestion of food goitrogens, but these phenomena are rare in North America. [merckmanuals.com]

The routine use of iodized table salt now helps prevent this deficiency. Risk factors are being female, being older than 40, having an inadequate dietary intake of iodine, living in an endemic area, and having a family history of goiters. [uclahealth.org]

Prevention To prevent toxic nodular goiter, treat hyperthyroidism and simple goiter as your provider suggests. [account.allinahealth.org]

Large goiters occasionally require surgery or iodine-131 to shrink the gland enough to prevent interference with respiration or swallowing or to correct cosmetic problems. Thyroid function is usually normal. [merckmanuals.com]
