A Child with Papillary Thyroid Carcinoma: Role of Radioactive Iodine Therapy in Pediatric Patients
A 13-year-old girl with a family history of thyroid carcinoma underwent thyroid ultrasound. A hypoechoic thyroid nodule with a 4 cm diameter was detected on the right thyroid lobe accompanying enlarged central compartment lymph nodes. Thus, the patient underwent total thyroidectomy and bilaterally central compartment lymph node dissection. Pathological examination revealed a conventional subtype papillary thyroid carcinoma located on the right thyroid lobe with a 4 cm diameter. Contrast-enhanced tomography of the thorax showed multiple metastatic nodules in both lungs. The patient was referred for radioiodine treatment (RAT) with a T3N1aM1 tumor. During radioiodine treatment, serum thyroglobulin (Tg) levels were measured as >472 ng/ml. Posttreatment I-131 whole-body scintigraphy showed multiple radioactivity accumulations in the neck and both hemithoraces.
