Background: Ultrasonography is considered useful to distinguish between solid and cystic thyroid nodules and to stratify a nodule's risk of cancer as low, medium, or high. Ultrasound (US) elastography has been applied to study the hardness/elasticity of nodules to differentiate malignant from benign lesions. Elastography possibly can solve the dilemma in reaching an accurate diagnosis for the cytologically known as indeterminate nodules.
Aim: To evaluate the sensitivity and specificity of US elastography in the diagnosis of thyroid cancer.
Patients And Methods: This prospective study included 40 patients. The total number of nodules was 46, they were all euthyroid. Laboratory investigations were done including FT3, FT4, and TSH to exclude hot nodules. Neck US, US elastography, and fine-needle aspiration were done to all patients, and US elastography scoring system from 1 to 4 was used.
Results: Four out of the 46 studied nodules were malignant. The ROC curve for elastography score (E-score) showed high sensitivity, specificity for the diagnosis of malignant thyroid nodules with a cut-off value of E-score 4 and high significance (p<0.001), the area under curve was 0.92. The sensitivity was 75.0% and specificity was 100%. For E-score more than 2, the sensitivity was 100% and specificity was 85.37%.
Conclusion: US elastography can be used to increase both the sensitivity and the specificity of US for the detection of malignant thyroid nodules, and so it seems to have great potential as a new tool for the diagnosis of thyroid cancer.

In the era of molecular testing, thyroid nodules with indeterminate cytology are increasingly being managed nonoperatively. The false-negative rates of these molecular tests, and therefore missed malignancies, are not well defined in real-world clinical practice. This retrospective study of patients undergoing fine needle aspiration (FNA) biopsy at our health system between November 2017 and March 2022 included nodules with The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) III and IV cytology and negative, currently negative, or negative but limited ThyroSeq version 3 (TSv3) results.

Rationale And Objectives: This study aims to develop a radiopathomics model based on preoperative ultrasound and fine-needle aspiration cytology (FNAC) images to enable accurate, non-invasive preoperative risk stratification for patients with papillary thyroid carcinoma (PTC). The model seeks to enhance clinical decision-making by optimizing preoperative treatment strategies.
Methods: A retrospective analysis was conducted on data from PTC patients who underwent thyroidectomy between October 2022 and May 2024 across six centers.

A 36-year-old woman with a history of neck swelling was diagnosed with papillary thyroid carcinoma, a common but typically slow-growing thyroid cancer with a good prognosis. Despite frequent lymph node metastasis, mortality rates are low. This cancer can rarely spread to unusual areas like the axillary region.
