Ultrasonography (US) is routinely used to evaluate thyroid nodules. The US features of papillary Epub ahead of print thyroid carcinoma (PTC), the most common thyroid malignancy, include hypoechogenicity, spiculated/microlobulated margins, microcalcifications, and a nonparallel orientation. However, many PTC variants have been identified, some of which differ from the classic type of PTC in terms of biological behavior and clinical outcomes. This review describes the US features and clinical implications of the variants of PTC...

BACKGROUND: The low rate of progression associated with the potential complications of thyroidectomy makes active surveillance an increasingly recommended management in low-risk papillary microcarcinomas of the thyroid (PMT). The objective of this study was to report the results of fine needle aspiration (FNA) of nodules ≤ 1 cm with highly suspicious appearance on ultrasonography (US) in patients who are potential candidates for active surveillance. METHODS: We revised thyroid nodules ≤ 1 cm with highly suspicious appearance on US in patients without known distant metastases, suspicion of extrathyroid extension, or suspicious lymph nodes on US...

BACKGROUND: Subclinical hypothyroidism (SH) is associated with adverse obstetric outcomes and neurodevelopment disorders. Both iodine deficiency and excess are associated with SH; however, few data regarding iodine nutrition status of pregnant women with SH are available. This study aimed to clarify whether iodine deficiency or excess is associated with SH, especially, when test results for anti-thyroid autoantibodies are negative. METHODS: A total of 115 women with SH and 104 women with euthyroidism (EH) in early pregnancy in Tianjin, China were investigated, and their serum thyroid-stimulating hormone, free thyroxine, free triiodothyronine, anti-thyroid peroxidase antibody (TPOAb), anti-thyroid globulin antibody (TGAb), urinary iodine (UIC), and urinary creatinine (UCr) concentrations were measured...

BACKGROUND AND PURPOSE: Core needle biopsy of the thyroid under ultrasonographic guidance provides a larger tissue sample and may facilitate a more precise histologic diagnosis, reducing the need for repetitive fine-needle aspiration or a diagnostic operation. However, there is no consensus regarding the ideal number of specimens to be obtained for ultrasonography-guided core needle biopsy. The aim of this study was to decide the ideal core number for ultrasonography-guided core needle biopsy of cytologically inconclusive nodules...

When patients are on long-term dialysis, various kinds of medication are given. We report our experience with a 75-yearold woman with thyroid carcinoma incidentally discovered during dialysis. Ultrasonography of the thyroid showed a tumor of about 3 cm in the right lobe center. The dialysis performed surgery on the day when we were not dialyzed. Heparinization for anticoagulation was not administered. Adhesion with the circumferential organ was strong, and in the perioperative findings, the thyroid gland showed difficulty in sublation...

A 73-year-old woman visited our hospital 1 year 4 months ago because of multiple lung masses that were incidentally detected on CT. We subsequently conducted a whole body examination. Ultrasonography revealed multiple masses in her thyroid. We performed fine needle aspiration biopsy cytology(ABC), and the cytological diagnosis was papillary carcinoma. Total thyroidectomy and modified radical neck dissection were performed. Two months after the operation, cervical lymph nodes were enlarged, and she received I -131 radioisotope therapy...

BACKGROUND: Hypothyroidism is a common sequel after a hemithyroidectomy. Although various risk factors leading to hypothyroidism have been reported, the effect of the contralateral lobe's volume has been understudied. This study aimed to examine the association between the preoperative contralateral lobe's volume and the risk of postoperative hypothyroidism. METHODS: During a 2-year period, 150 eligible patients undergoing a hemithyroidectomy were evaluated. The volume of the contralateral nonexcised lobe was estimated preoperatively by independent assessors on ultrasonography using the following formula: width (in cm) × depth (in cm) × length (in cm) × (π/6), adjusted for the body surface area (BSA)...

Seung Taek Lim, Ye Won Jeon, Young Jin Suh
Purpose: The current TNM staging system for papillary thyroid cancer (PTC), which is based on tumor diameter, may not precisely reflect the true tumor burden. Therefore, we investigated whether preoperative tumor volume might more accurately reflect tumor burden and predict prognosis in patients with T1N0 PTC than preoperative tumor diameter. Materials and Methods: We retrospectively reviewed data from 1,659 patients with T1N0 PTC, and after exclusion, a total of 1,081 patients were ultimately included...

REVIEW
Stavroula Α Paschou, Andromachi Vryonidou, Dimitrios G Goulis
Thyroid nodules constitute by far the most common disorder of the endocrine system. Epidemiological studies have indicated that approximately 5% of women and 1% of men resident in iodine-sufficient areas have palpable thyroid nodules. However, by the age of 60 years about 50% of the general population is estimated to have at least one thyroid nodule. Indeed, the reported prevalence of a "thyroid incidentaloma" is up to 70% when neck/carotid artery ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) is performed for other indications...

A 73-year-old man displaying primary hyperparathyroidism with severe hypercalcemia (Ca: 4.1 mmol/l, PTH > 600 pmol/l) was referred for preoperative localization of a parathyroid adenoma. Tc-pertechnetate and Tc-sestaMIBI dual tracer scintigraphy displayed a mild focal uptake in the projection of the right thyroid lobe with negative ultrasonography. F-Fluorocholine PET/CT was quickly performed considering this discrepancy and not only confirmed the scintigraphic findings but also revealed a second contralateral focus of increased uptake, both later confirmed by operative consideration (the two other parathyroid glands are considered normal by the surgeon), pathology, and intraoperative parathyroid hormone assessment...
