Lymph node metastasis (LNM) is the primary challenge in papillary thyroid cancer (PTC). Recurrent cancerous lymph nodes require repeated surgeries, which increases the risk for surgical complications. Thus, the evaluation of LNM before surgery is important. Ultrasonography is the most convenient way to examine cervical LNM, but the sensitivity of ultrasonography in the identification of LNM in cases of PTC is extremely low. A series of lncRNAs (long noncoding RNAs) have been reported as candidate biomarkers in a variety of tumors...

BACKGROUND: Struma ovarii (SO) is a specialized monodermal teratoma predominantly composed of mature thyroid tissue, accounting for approximately 5% of all ovarian teratomas. Thyrotoxicosis is seen in about 8% of patients with SO. Most SO cases are benign with only 5-10% being malignant, and malignant SO causing thyrotoxicosis is very uncommon. CASE: A 64-year-old woman had been diagnosed with thyrotoxicosis 2 years previously. The thyroid gland was palpable with a micronodular texture, and the patient was euthyroid under carbimazole...

OBJECTIVE: Incidentally discovered thyroid cancers (IDTC) contribute to the rapid rise in thyroid cancer incidence over the past 20 years. Since death rates from thyroid cancer are not increasing, we hypothesized that IDTC are less aggressive compared to those whose cancers are clinically apparent (CATC). METHODS: A retrospective study of patient and tumor characteristics of IDTC and their rates of residual/recurrent (R/R) disease were determined at a median follow-up of 27 months in the setting of a large academic medical center...

We report a case of incidental uptake of 99mTc-methylene diphosphonate in the thyroid in a 62-year-old female with a history of breast cancer treated with quadrantectomy, chemotherapy and radiotherapy, who underwent total-body-bone scintigraphy during follow up. Planar scintigraphy was followed by neck SPECT-CT that demonstrated an area of increased tracer uptake in the neck at the left lobe of the thyroid. Neck ultrasonography showed a nodule corresponding to SPECT-CT finding and the ultrasound-guided fine needle aspiration documented the presence of papillary carcinoma...

PURPOSE: To assess the accuracy and reproducibility of ultrasonography classification systems in characterizing cytologically indeterminate thyroid nodules. METHODS: We retrospectively identified 49 nodules that had been surgically resected owing to features classified as indeterminate according to 2010 Italian Consensus on Thyroid Cytology criteria. Three experienced sonographers independently reviewed original sonographic images of each nodule and classified it using the 2015 American Thyroid Association (ATA) guidelines and the Thyroid Imaging Reporting and Data System (TI-RADS) classification proposed by Korean radiologists; later, images were reviewed jointly to obtain consensus classifications of each nodule...

A 45-year-old woman with a differentiated thyroid carcinoma received adjuvant radioiodine therapy following total thyroidectomy and left modified radical neck dissection. A posttherapy planar radioiodine scan showed multifocal uptake in the thyroid bed and left chest. SPECT/CT revealed a fibroadenoma in the left breast. Six months later, an I scan showed no iodine avidity in the breast fibroadenoma, whereas ultrasonography showed no significant change in the size of the fibroadenoma. Altered radioiodine uptake of a breast fibroadenoma can be observed on follow-up scans after cytotoxic radioiodide treatment in patients with differentiated thyroid carcinoma...

Optimal treatment of thyroid cancer is highly dependent on accurate staging of the extent of disease at presentation. Preoperative ultrasonography (US) is the most sensitive method for detecting metastatic lymph nodes and is recommended as part of the standard preoperative workup. Missed findings on preoperative scans may lead to understaging and inadequate surgical management, which subsequently predispose these patients to residual disease postoperatively and a higher risk for recurrence, possibly requiring repeat surgery...
