A person has fever & pain in thyroid gland. True statement(s) is/are:
**Core Concept**
The thyroid gland can become inflamed due to various causes, leading to pain and swelling, a condition known as thyroiditis. This inflammation can result from an autoimmune response, viral infections, or other factors that trigger an immune reaction against the thyroid gland.
**Why the Correct Answer is Right**
Thyroiditis can present with symptoms such as pain and swelling in the thyroid gland, as well as fever, due to the inflammatory response. The condition can be caused by an autoimmune response, as seen in conditions like Hashimoto's thyroiditis, or by viral infections, such as subacute thyroiditis. In both cases, the body's immune system mistakenly attacks the thyroid gland, leading to inflammation and symptoms.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because while thyroid nodules can cause pain and discomfort, they are not typically associated with systemic symptoms like fever.
**Option B:** This option is incorrect because thyroid cancer is a malignant condition that may cause pain and discomfort, but it is not typically associated with fever.
**Option C:** This option is incorrect because hyperthyroidism can cause symptoms like weight loss and tremors, but it does not typically cause pain and swelling in the thyroid gland.
**Clinical Pearl / High-Yield Fact**
It is essential to distinguish between thyroiditis and other conditions that can cause thyroid gland pain and swelling, such as thyroid nodules or cancer. A thorough history and physical examination, as well as diagnostic imaging and laboratory tests, can help determine the underlying cause of symptoms.
**Correct Answer: C.** Thyroiditis can present with symptoms such as pain and swelling in the thyroid gland, as well as fever.
