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 ...

Although many who experience this worry that it is thyroid cancer, there are many causes of nodules that are benign and not cancerous. If a possible nodule is present, a doctor may order thyroid function tests to determine if the thyroid gland's activity is being affected.

Thyroid ultrasonography is the modality of choice for thyroid evaluation. [1] Yet, focal and diffuse thyroid abnormalities [2] are commonly encountered during the interpretation of computed tomography (CT) exams performed for various clinical purposes. [1] For example, CT often detects incidental thyroid nodules (ITNs).
Thyroid follicular adenoma ranges in diameter from 3 cm on an average, but sometimes is larger (up to 10 cm) or smaller. The typical thyroid adenoma is solitary, spherical and encapsulated lesion that is well demarcated from the surrounding parenchyma. The color ranges from gray-white to red-brown, depending upon. the cellularity of the adenoma.
Colloid nodules, also known as adenomatous nodules[1] or colloid nodular goiter[2] are benign, noncancerous enlargement of thyroid tissue. [3] Although they may grow large, and there may be more than one, they are not malignant and they will not spread beyond the thyroid gland. Colloid nodules are the most common kind of thyroid nodule.
Papillary thyroid cancer (papillary thyroid carcinoma, [1] PTC) is the most common type of thyroid cancer, [2] representing 75 percent to 85 percent of all thyroid cancer cases. [1] It occurs more frequently in women and presents in the 20–55 year age group. It is also the predominant cancer type in children with thyroid cancer, and in ...
