PURPOSE: The effect of ultrasonography (US)-guided fine-needle aspiration (US-FNA) for the collapse of benign cystic thyroid nodules is still unclear. This study aimed to assess the positive response rate following US-FNA of the cystic component of thyroid cysts and of partially cystic thyroid nodules (PCTNs), and to evaluate the factors influencing the outcome. METHODS: From June to December 2013, seven radiologists at seven institutions prospectively performed US-FNA on 320 cystic thyroid nodules in 320 patients...

Medullary thyroid carcinoma (MTC) in multiple endocrine neoplasia type 2 (MEN2) is an autosomal dominant disorder caused by the mutation of the RET proto-oncogene, that shows nearly complete penetration. The American Thyroid Association guidelines recommend prophylactic thyroidectomy for patients with high-risk RET mutations. However, in Japan, ethical and medical issues may preclude prophylactic treatment in young patients. Hence, an early diagnosis of MTC is necessary to ensure a favorable outcome. Here, we report the case of a young Japanese girl with a high-risk RET mutation, diagnosed with very early stage MTC using serum calcitonin (Ctn) values measured using an electro chemiluminescence immuno-assay (ECLIA)...

A thyroid nodule detected clinically or incidentally at medical imaging is a common indication for ultrasonography (US) in the adult population. This scenario is less frequently the case in pediatric patients, and the approach to evaluation of thyroid nodules deserves modification in these patients because of the increased probability of malignancy in children, compared with adults. Evaluating a thyroid nodule with US in a systematic way requires familiarity with a number of features that can be assessed and the terms that the radiologist uses in each category...

We reviewed the current status of thyroid fine needle aspiration cytology (FNAC) in Korea. Thyroid aspiration biopsy was first introduced in Korea in 1977. Currently, radiologists aspirate the thyroid nodule under the guidance of ultrasonography, and cytologic interpretation is only legally approved when a cytopathologist makes the diagnosis. In 2008, eight thyroid-related societies came together to form the Korean Thyroid Association. The Korean Society for Cytopathology and the endocrine pathology study group of the Korean Society for Pathologist have been updating the cytologic diagnostic guidelines...

BACKGROUND: Among patients with papillary thyroid carcinoma (PTC), 30%-80% have cervical lymph node (LN) metastases, which are most commonly located in the central compartment. However, preoperative ultrasonography identifies malignant central compartment LNs in only 20%-30% of cases. We aimed to evaluate the diagnostic value of intraoperative thyroglobulin (Tg) measurement in fine-needle aspirates (FNA-Tg) of suspicious metastatic LNs. METHODS: In total, 75 patients (75 LNs) with PTC or suspected PTC were enrolled in this study...

OBJECTIVES: Selenium (Se) deficiency is related to an increased risk of preterm labor, miscarriage, preeclampsia, gestational diabetes, and other obstetric complications. As the Se status declines during pregnancy, we hypothesized that the decline may be exacerbated in women with autoimmune thyroid disease (AITD). MATERIAL AND METHODS: Pregnant women (n=74; 30 [23-38] years) were consecutively recruited from the district of Warsaw, Poland, and divided into healthy subjects (HS, n=45), and women with a diagnosis of AITD (AITD, n=29)...

Two types of risk stratification system, i.e., a qualitative grading system or a quantitative scoring system, have been used for the effective management of thyroid nodules on ultrasonography (US). The concept of Thyroid Imaging Reporting and Data System (TI-RADS), based on the quantitative scoring system, was introduced in the late 2000s and its format has been constantly evolving and developing. Understanding the role and appropriate utilization of risk stratification systems including TI-RADS could facilitate the effective interpretation and communication of thyroid US findings among referring physicians and cytopathologists...

BACKGROUND: Surgery is the elective treatment for cervical relapse from differentiated thyroid cancer (DTC) but it is technically challenging, with risk of failure and morbidity. We explored the feasibility and the efficacy of Radioguided Occult Lesion Localization (ROLL) with intratumoral 99mTc radiolabeled human albumin macroaggregates ([99mTc]MAA) injection in this setting. METHODS: Fifteen patients who underwent ROLL by ultrasonography (US)-guided intratumoral injection of [99mTc]MAA between December 2013 and October 2016 for DTC recurrence were considered for this study...

Pharyngoesophageal diverticula (PED) of the Zenker's and Killian-Jamieson types arise in close proximity to the thyroid gland, and may rarely be confused with a thyroid nodule on ultrasonography. In this brief report, we detail the cytologic, clinical, and radiologic findings of three PED that were thought to be thyroid nodules, and were subjected to fine-needle aspiration (FNA). The patients were females with an age range of 51-64 years. All three patients had multiple thyroid nodules, and two patients reported symptoms attributable to the diverticulum...

An 18 years-old-girl presented one and half years back with the complaints of short stature, retarded growth, and menorrhagia with sudden severe lower abdominal pain; was diagnosed as bilateral ovarian cysts and underwent bilateral ovarian cystectomy. Later on she was incidentally diagnosed as a case of hypothyroidism when she had been experiencing slowly enlarging left lower abdominal mass with dull ache for the 5 month and then was transferred to the department of Endocrinology for further evaluation. Detailed work up revealed her short stature with obesity, delayed bone age and other features of hypothyroidism which was confirmed by thyroid function testing...

Renal metastasis of thyroid cancer is extremely rare. We report the case of a 62-year-old woman with Hürthle cell thyroid cancer (HCTC) with lungs, bones, and bilateral kidneys metastases. The renal metastatic lesions were clearly demonstrated by (131)I whole body scan (WBS) with SPECT/CT. However, they exhibited false-negative results in (18)F-FDG PET/CT, kidney ultrasonography, and contrast-enhanced CT scan. The findings imply that tumors have low glucose metabolism and are able to accumulate radioiodine, which is not commonly found in the relatively aggressive nature of HCTC...
