Background: The majority of thyroid nodules are clinically insignificant, however considerable overlap in radiological characteristics exists for benign and malignant lesions. Recently, validated radiological criteria using thyroid imaging reporting and data system scoring (TIRADS) have shown correlation between cumulative suspicious features and risk of malignancy1.Objective: To assess sensitivity, specificity and reliability of ultrasound sc...

Use of 18F-FDG-PET/CT (PET) staging for a variety of malignancies has increased in recent years. A rise in detection of incidental thyroid lesions creates a novel diagnostic challenge. We present four cases of Thyroid PET positivity.A 62-year-old lady with pulmonary adenocarcinoma on contrast CT-Thorax had diffuse thyroid PET uptake. Biochemistry revealed a self-limiting TSH rise. Thyroid ultrasound showed benign nodular goitre (U2). Findin...

Although the vast majority of thyroid nodules are benign, evaluation by ultrasound-guided fine needle aspiration (FNA) biopsy is usually necessary to exclude underlying malignancy. Partially in recognition of reported variability in FNA sensitivity and specificity, the 2007 British Thyroid Association (BTA) guidelines recommended two benign results 3–6 months apart to exclude neoplasia. The 2014 BTA guidance states that a second FNA is not required for nodules with benign...
