국문 초록 (Abstract)

저자들은 신생아 선별 검사상 갑상선 기능저하증을 보인 신생아에서 경부초음파검사, 방사선 동위원소 스캔을 통하여이중 이소성 갑상선을 진단하고, L-thyroxine을 투여하여 정상발육하고 있는 1례를 경험하였기에 보고하는 바이다.

다국어 초록 (Multilingual Abstract)

An ectopic thyroid occurs when thyroid tissue has not properly migrated from the foramen cecum to the fourth tracheal ring along the midline of the ventral portion of the neck, but instead is located elsewhere. There are some cases of dual-site ectopic thyroid glands, usually involving adolescents or adults. Cases of neonatal dual ectopic thyroid glands are even rarer. We report a case of a dual ectopic thyroid with congenital hypothyroidism found during a neonatal screening of the lingual and upper cervical regions of a patient . The patient had no airway obstruction symptoms, such as dysphagia or grunting. The thyroxine (T4) level was 2.49 μg/dL (normal value: 6.2-22.0 μg/dL)and the thyroid-stimulating hormone (TSH) level was 217.85 μIU/mL (normal value: 1.7-9.1 μIU/mL). A dual ectopic thyroid was diagnosed based on a Tc-99m thyroid scan. After receiving thyroid hormone replacement therapy, the child has developed normally
