There are a heterogeneous enlarged lymph nodes at level 2 and 3 with markedly increased vascularity (white arrow in b and c). d–f Enhanced axial CT images of the neck demonstrate a 2.7 × 1.4 cm hypodense soft tissue lesion anterior to the left carotid sheath (white arrow).
Hypervascularity is an increased number or concentration of blood vessels. In Graves disease, the thyroid gland is hypervascular, which can help in differentiating the condition from thyroiditis. [1] 90% of thyroid papillary carcinoma cases are hypervascular.
Thyroid nodules are nodules (raised areas of tissue or fluid) which commonly arise within an otherwise normal thyroid gland. [1] They may be hyperplastic or tumorous, but only a small percentage of thyroid tumors are malignant. Small, asymptomatic nodules are common, and often go unnoticed. [2] Nodules that grow larger or produce symptoms may ...
This causes increased vascularity and increase in size (hypertrophy) of the gland. [9] In hypothyroid states or iodine deficiency, the body recognizes that it is not producing enough thyroid hormone and starts to produce more TSH to help stimulate the thyroid to produce more thyroid hormone. [9] This stimulation causes the gland to increase in ...
The thyroid gland is a butterfly-shaped organ composed of two lobes, left and right, connected by a narrow tissue band, called an "isthmus". [4] It weighs 25 grams in adults, with each lobe being about 5 cm long, 3 cm wide, and 2 cm thick and the isthmus about 1.25 cm in height and width. [4]
Hyperaemia (also hyperemia) is the increase of blood flow to different tissues in the body. It can have medical implications but is also a regulatory response, allowing change in blood supply to different tissues through vasodilation (widening of blood vessels). Clinically, hyperaemia in tissues manifests as erythema (redness of the skin ...
2% at some point [4] Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis and Hashimoto's disease, is an autoimmune disease in which the thyroid gland is gradually destroyed. [1][6] A slightly broader term is autoimmune thyroiditis, identical other than that it is also used to describe a similar condition without a goiter. [7 ...
003444. [edit on Wikidata] Thyroid function tests (TFTs) is a collective term for blood tests used to check the function of the thyroid. [1] TFTs may be requested if a patient is thought to suffer from hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), or to monitor the effectiveness of either thyroid-suppression or ...
