To correlate the size of autonomously functioning thyroid nodules (AFTN) with thyroid function tests. A retrospective analysis of data from patients with a diagnosis of a single AFTN who were seen in a university-based endocrinology clinic between January 1, 2003 and December 31, 2015 was performed. Patients with a nuclear thyroid scan confirming the presence of an AFTN without significant cystic degeneration were included in the study. The volume of the AFTN and the corresponding thyroid function tests were compared in 32 patients who met inclusion criteria. There was no correlation between the volume of the AFTN and thyroid stimulating hormone (TSH) levels (r = 0.044). There was also no volume threshold below which an AFTN was always associated with a TSH within the reference range. The results agree with the findings of other recent studies comparing the volume of AFTNs with TSH levels, suggesting that smaller nodules can still demonstrate subclinical and overt hyperthyroidism and a normal TSH level does not preclude the presence of an AFTN.

To compare the efficacy of Radioiodine (RI) and Radiofrequency ablation (RFA) in the treatment of autonomously functioning thyroid nodules (AFTNs).
Thyroid nodules and thyroid cancer discovered during pregnancy can result in significant anxiety for patients may present a challenge for providers. The prevalence of thyroid nodules is reported to va...
Image-guided thermal ablations are commonly used in the treatment of thyroid nodules. Radiofrequency ablation (RFA) and laser ablation are the most commonly used. Here we aimed to obtain solid evidenc...
This study was designed to explore whether ultrasound of thyroid nodules facilitates the interpretation of the malignant risk of Bethesda III/IV thyroid nodules to inform further therapies.
Thyroid ultrasound is used as a first-line diagnostic procedure to evaluate thyroid nodules. Several ultrasound characteristics have been associated with an increased risk of malignancy. Based on thes...
Thyroid nodules are a common presentation in the clinic, with an increasing incidence, especially in women. Their clinical significance is mainly related to excluding malignancy (4.0 to 6....
Nowadays, the investigation of thyroid nodules is limited by the fact that up to 49% of the fine needle aspirations (FNA) performed on them are of "indeterminate cytological signification"...
Ultrasound-guided ethanol ablation is an effective treatment modality for patients with cystic thyroid nodules (cystic portion > 90%); however it is less effective in predominantly cystic ...
Nodular goitre is common in the general population and less than 5% of the patients who undergo surgery for solitary thyroid nodules have cancer, in absence of clinical suspicion. Nodu...

A small circumscribed mass in the THYROID GLAND that can be of neoplastic growth or non-neoplastic abnormality. It lacks a well-defined capsule or glandular architecture. Thyroid nodules are often benign but can be malignant. The growth of nodules can lead to a multinodular goiter (GOITER, NODULAR).
An enlarged THYROID GLAND containing multiple nodules (THYROID NODULE), usually resulting from recurrent thyroid HYPERPLASIA and involution over many years to produce the irregular enlargement. Multinodular goiters may be nontoxic or may induce THYROTOXICOSIS.
Blood tests used to evaluate the functioning of the thyroid gland.
An aggressive THYROID GLAND malignancy which generally occurs in IODINE-deficient areas in people with previous thyroid pathology such as GOITER. It is associated with CELL DEDIFFERENTIATION of THYROID CARCINOMA (e.g., FOLLICULAR THYROID CARCINOMA; PAPILLARY THYROID CANCER). Typical initial presentation is a rapidly growing neck mass which upon metastasis is associated with DYSPHAGIA; NECK PAIN; bone pain; DYSPNEA; and NEUROLOGIC DEFICITS.
The smallest difference which can be discriminated between two stimuli or one which is barely above the threshold.
The thyroid is a butterfly-shaped gland in the neck, just above thecollarbone and is an endocrine gland that make hormones. These Thyroid hormones control the rate of many activities in the body, including how fast the body burns calories and how fast th...
