THYROID DISEASES IN CHILDREN AND ADOLESCENTS, ORBAK ZERRİN,HASPOLAT YUSUF KENAN, Editör, ORIENT PUBLICATIONS, Ankara, ss.105-118, 2023
There are various diseases of the thyroid gland in pediatric and adolescent age group and early diagnosis of some of those diseases like congenital hypothyroidism is very important in pediatric development. Radiology plays a key role in the di agnosis with thyroid function tests. Ultrasonography (US) is the first line modality used in thyroid imaging in children and adolescents along with scintigraphy. In this chapter, we will review key diagnostic imaging features of the normal thyroid gland, congenital abnormalities, diffuse and focal diseases of the thyroid gland. T hyroid diseases in pediatric and adolescent patients are important as early detection in certain cases can affect the development of the patient (1). Ultrasonography (US) is the first line modality used in thyroid imaging in children and adolescents along with scintigraphy. Computed tomography (CT) or Magnetic Resonance Imaging (MRI) are complementary imaging modalities in rare situations for thyroid diseases in children. T he advantages of US are radiation free technique, easily accessible and low cost but the disadvantage is that it is operator dependent. High-resolution ultrasound with thyroid function tests provides diagnosis in almost all the cases with the use of scintigraphy in certain situations. Common indications for pediatric thyroid ultrasound are evaluation of congenital hypothyroidism, palpable lump in the thyroid or in the migration pathway, screening carcinomas and follow up nodules (2). In this chapter, we will focus on the key diagnostic imaging features of the congenital abnormalities, diffuse thyroid diseases and focal pathologies.
