  2. Riedel's thyroiditis - Wikipedia

    en.wikipedia.org/wiki/Riedel's_thyroiditis

    Patients may present with symptoms of hypothyroidism and hypoparathyroidism as the gland is replaced by Fibrous tissues . Physical examination reveals a hard "woody" thyroid gland with fixation to surrounding tissue. [4] The diagnosis needs to be confirmed by open thyroid biopsy because the firm and Fibrous nature of the gland renders FNAB ...

  3. ICD coding for rare diseases - Wikipedia

    en.wikipedia.org/wiki/ICD_coding_for_rare_diseases

    Europe and other parts of the world use the ICD-10. The root codes for ICD-10 and ICD-10-CM are the same, making it helpful for locating codes for general body systems and disease processes. [2] [3] In ICD-11 the search and coding of any disease, including rare ones is done via the ICD-11 website. [4]

  4. Graves' disease - Wikipedia

    The TSHr is expressed on the thyroid follicular cells of the thyroid gland (the cells that produce thyroid hormone), and the result of chronic stimulation is an abnormally high production of T3 and T4. This, in turn, causes the clinical symptoms of hyperthyroidism, and the enlargement of the thyroid gland visible as goiter.

    Measurement of thyroid stimulating hormone and anti-thyroid antibodies will help decide if there is a functional thyroid disease such as Hashimoto's thyroiditis present, a known cause of a benign nodular goitre. [4] Fine needle biopsy for cytopathology is also used. [5] [6] [7] Thyroid nodules are extremely common in young adults and children.

  8. De Quervain's thyroiditis - Wikipedia

    Thyroid ultrasonography typically shows thyroid gland enlargement and hypoechogenicity, while color Doppler ultrasonography may show low or normal vascular flow. Tissue diagnosis is rare, but fine needle aspiration may be helpful in questionable cases to differentiate unilateral involvement from bleeding into a cyst or tumor.

  9. Subacute thyroiditis - Wikipedia

    en.wikipedia.org/wiki/Subacute_thyroiditis

    [1] [4] [5] The thyroid gland may be firm, finely nodular, and may or may not be diffusely enlarged. [ 4 ] [ 5 ] Similar to subacute granulomatous thyroiditis, there is an initial transient thyrotoxic phase that can last 2-5 months followed by a hypothyroid phase.
