Abstract

The initial presentation of distant metastases in patients with papillary thyroid carcinoma is quite rare. Most distant metastases are solid nodular lesions. A 67-year-old man who complained of severe dyspnea underwent surgery due to a large mediastinal cystic mass compressing the trachea and great vessels. Pathologically, the cystic mass was a metastatic thyroid papillary carcinoma. The thyroid evaluations were compatible with a well differentiated thyroid carcinoma. An occult thyroid carcinoma presenting as a large mediastinal cystic lesion is extremely rare.

심한 호흡곤란을 주소로 내원한 67세 남자의 영상소견상 종격동의 거대 낭성 종양이 기관을 압박하여 편이시키는 소견이 보여 응급 개흉술을 통해 종양을 절제하였다. 조직 소견상 갑상선의 유두상 암종에 합당하였고 수술 후 시행한 갑상선 초음파 검사와 양성자 단층촬영상 잠재성 갑상선 암종에 합당한 소견을 보였다. 갑상선의 유두상 암종이 초기에 원격 전이를 보이는 경우는 드물며 대부분 단독 결절의 형태를 취하나, 잠재성 암종이 종격동에 거대 낭성 전이를 하는 경우는 극히 드물어 보고하는 바이다.
