갑상선 반쪽 무형성증은 갑상선의 한쪽 엽이 형성되지 않는 드문 선천성 갑상선 질환이다. 갑상선 반쪽 무형성증 자체는 대개 아무런 임상 증상을 초래하지 않으므로 대부분은 동반된 갑상선 질환을 진단하는 과정이나 수술 중에 우연히 발견된다. 저자들은 선천성 갑상선기능저하증이 의심되어 내원한 1개월된 영아에서 원인을 찾던 중에 갑상선 초음파 및 스캔 검사를 통해 갑상선 반쪽 무형성증을 진단하였기에 보고하는 바이다.

Thyroid hemiagenesis is a very rare congenital anomaly in which one thyroid lobe fails to develop. The cause of thyroid hemiagenesis is still unknown. The true prevalence of thyroid hemiagenesis is not known, but it is estimated to be from 0.05% to 0.2% in normal children. Thyroid hemiagenesis is common in female with the left lobe being absent. The common disease in the remaining lobe is hyperthyroidism, benign adenoma, a toxic multinodular goiter, chronic thyroiditis, primary myxedema, and rarely carcinoma. Tc-99m pertechnate scintigraphy, ultrasonography and computerized tomography can be used to confirm this anomaly. Here we report three cases with left lobe agenesis. Two of them were euthyroid state while the other hypothyroid patient had a ectopic lingual thyroid.

Thyroid hemiagenesis is rare congenital anomaly that one lobe of thyroid fails to develop. It is often asymptomatic and discovered incidentally with other thyroid disease such as hypothyroidism, hyperthyroidism, multinodular goiter, benign adenoma and cancer. Most cases reported are left thyroid lobe agenesis and occurred in female. Compensatory hypertrophy occurs in most cases. Many cases are asymptomatic and detected incidentally, so awareness of its existence can help its detection and proper treatment. Here, we report a case of thyroid hemiagenesis accompanying hypothyroidism with a review of literature.

Thyroid hemiagenesis is a rare anomaly, which is the result of failure of embryologic development of a lobe of thyroid gland. It is more frequently found in the left lobe and in female patients. We, herein, report an extremely rare case of thyroid hemiagenesis associated with papillary thyroid carcinoma. A 69-year-old female presented with an incidentally discovered thyroid nodule in the right thyroid during a routine medical check-up. Ultrasonography(US) and computed tomography(CT) disclosed $0.7{\times}0.5cm\;and\;2.8{\times}2.2cm$ sized nodules in the right thyroid. The left thyroid, however, was not seen in the imaging studies of US and CT. Fine-needle aspiration of the small and large nodules showed papillary thyroid carcinoma and adenomatous hyperplasia, respectively. The patient underwent a right total thyroidectomy with central compartment node dissection. The operative findings and histologic examination confirmed the absence of the left thyroid associated with papillary thyroid carcinoma and ademonatous hyperplasia of the right thyroid.

1) 선천성 갑상선 발육이상 환자 9명 모두, 경부종피를 호소하였으며, 이 중 1예는 연하통을 동반하였다. 2) 선천성 갑상선 발육이상을 세분하여보면, 이소성갑상선이 44.4%,편측발육부전 및 이소성갑상선을 동반한 경우가 33.3%였고, 편측발육부전을 보인 경우가 22.2%였다. 3) 이소성갑상선을 위치별로 보면 설기저부가 6예(85.7%-1예 중복됨), 갑상설관이 2예였다. 4) 정상 갑상선기능을 보인 경우가 77.8%였고, 갑상선기능저하증을 보인 경우가 22.2%였다. 정상기능을 보인 7명의 환자 중 4명에서 갑상선자극호르몬(TSH)이 증가되어 있었다. 5) 총 9명중 7명에서는 갑상선억제요법만 시행하였고, 2명에서는 갑상선억제요법에 반응하지 않아 절제술을 시행하였으며, 2명 모두 설갑상선이었다. 수술후 계속적으로 갑상선호르몬을 복용중이다.
