The majority of this talk will be used to describe and illustrate the sonographic features that are associated with thyroid cancer, briefly looking at the supporting evidence. I will also review some cross-sectional and functional imaging characteristics of thyroid malignancy and discuss the role of fine-needle aspiration cytology.Declaration of interest: There is no conflict of interest that could be perceived as prejudicing the impartiality of the rese...

Introduction and Objectives: Guidelines are available for the investigation of thyroid nodules. These include a general agreement that patients with abnormal thyroid function tests (TFTs) do not need routine ultrasound (US) assessment. Thyroid US is a common imaging request made by General Practitioners (GPs). This audit was devised to determine the range of clinical indications for GP thyroid US and the frequency with which TFTs are assessed by the GP prior to requesting the ...

A 24-year-old girl was referred with a massive thyroglossal duct cyst (TGDC) and an intra-cystic papillary thyroid cancer (PTC). The impressive clinical photographs, striking radiological images and histology slides are presented.She presented eight and half months post partum with a 10 cm midline neck lump of 4 years duration. She was asymptomatic and was on levothyroxine for Hashimoto’s thyroiditis.Clinically, there was a cy...

A 24-year-old woman presented with stridor resulting from a large, firm, anterior neck mass. At age six she had been treated for acute lymphoblastic leukaemia (ALL) with vincristine, prednisolone, daunorubicin, asparaginase, prophylactic cranial radiotherapy and intrathecal methotrexate. She also had primary hypothyroidism with strongly positive thyroid peroxidase antibodies.The mass had been gradually enlarging for 6 months, causing exertional breathles...

Background: Patients being treated for differentiated thyroid cancer (DTC) receive a dose of Radioiodine for remnant ablation. Occasional patients appear to have little or no iodine uptake at all in the thyroid bed or else where even shortly after thyroidectomy.Objective: To evaluate the influence of ‘Coexisting Thyroiditis’ on radioiodine uptake in thyroid cancer ablation doses.Methods and Design: Retrospec...

Introduction: Germline mutations in succinate dehydrogenase subunit B (SDHB) are one of the commonest findings in familial paraganglioma (PGL) syndromes and account for one quarter of PGLs associated with germline mutations. Although the penetrance is low, the malignancy conversion is high; up to 30%. With the increasing availability of genetic testing and the identification of ‘asymptomatic carriers’ of the SDHB gene mutation, it is therefore impor...
