Contrast-enhanced ultrasound (CEUS) and shear wave elastography (SWE) have been widely studied in adult thyroid disease. However, evaluation of thyroid nodules using these tools in pediatric patients has yet to be published.
We aim to evaluate the feasibility and safety of CEUS and SWE for thyroid nodules in children at the time of cytologic biopsy. Read More

Thyroid cancer is the most prevalent endocrine malignancy in the pediatric population. Accurate diagnosis and staging of thyroid carcinoma demand a multimodality approach, including anatomic imaging with US, CT, and MRI, alongside functional or metabolic nuclear imaging. Novel imaging techniques such as US elastography, contrast-enhanced US (CEUS), superb microvascular imaging (SMI) and dual-source dual-energy thyroid CT have offered non-invasive tools to assess disease status. Furthermore, the emerging field of radiomics/radiogenomics and artificial intelligence is continuously growing, creating models to classify or predict disease behaviour. We provide a comprehensive overview of the essential imaging characteristics of pediatric thyroid carcinoma using conventional and novel imaging techniques. In addition, we illustrate the multimodality, multidisciplinary, and collaborative approach across pediatric radiology and nuclear medicine in pre-operative, post-operative and post-treatment imaging surveillance of cancer thyroid in children.

High-resolution ultrasonography (US) is a valuable and accessible imaging tool to assess and characterize the thyroid gland in children. Pediatric thyroid nodules are infrequent. However, the incidence of thyroid carcinoma in children is near twice the adult population, where the risk of malignancy is up to 15%. Children also have an increased risk for recurrence (39%) as compared to adults, justifying further work and a more aggressive approach. Prompt recognition of the common and uncommon sonographic features of thyroid cancer in children will allow radiologist to identify this malignancy in early stages of the disease, expediting appropriate treatment improving the standard of patient care. The purpose of this exhibit is to 1. To illustrate the spectrum of sonographic findings of thyroid cancer in a pediatric population. 2. To describe the typical sonographic characteristics of malignant thyroid nodules in children. 3. To identify the uncommon features of pediatric thyroid cancer. 4. To describe an appropriate approach to deal with uncertain diagnosis. Read More

Ectopic thymic tissue may be found in the neck in up to 20% of the general population. Intrathyroidal thymic rest has been described as a rare entity, present in as many as 1% of children. The course of thymic migration parallels the thyroid and parathyroid glands, which explains their similar ectopic locations. While the natural history of these lesions has not been well studied, it is likely that there is involution of thymic rests with age. A few individual case reports have described the imaging features of intrathryoidal thymic rests confirmed by histopathology and flow cytometry. The aim of this case series is to raise awareness of the characteristic sonographic appearance of this entity to the radiology community. Read More

Several ultrasound (US) findings are associated with specific thyroid diseases, but in the vast majority of cases, only a few of these findings are seen. The purpose of this poster is to describe the US findings in a variety of clinically/biopsy-proven thyroid diseases and analyze the frequency of such findings in each of the following diseases.

Thyroid hemiagenesis (TH) is a rare congenital abnormality associated with a higher incidence of thyroid disease. It is often asymptomatic and an incidental finding. However, TH may present as a palpable thyroid nodule, prompting sonography and thyroid function testing. Ultrasound (US) can differentiate between total absence of the thyroid lobe and severe hypoplasia. It is also useful for guiding fine needle aspiration when warranted. Scintigraphy is useful for determining the presence of ectopic thyroid tissue and to further characterize focal nodular thyroid lesions. Despite their respective roles, imaging findings on both US and scintigraphy can pose diagnostic challenges to the pediatric radiologist.

This educational poster will review the embryology of the thyroid gland, frequency of TH, clinical presentation and associations with additional thyroid anomalies such as malignancy, thyroiditis and abnormal gland function. Imaging features of TH will be reviewed with focus on (US) and scintigraphy.

The goals of this exhibit are:
1. Review the incidence and clinical presentation of pediatric patients with TH
2. Describe the imaging findings and role of ultrasound and scintigraphy in the diagnosis and follow-up of TH
3. Discuss prognosis and outcomes of TH in children Read More
