Ectopic thyroid tissue has been found from the tongue to the diaphragm. The most common ectopic thyroid tissue has been found in the tongue, submandibular region, cervical lymph nodes, larynx, trachea, oesophagus, mediastinum, diaphragm and heart respectively. "Forgotten goiter" is an extremely rare disease which is defined as a mediastinal thyroid mass found after total thyroidectomy. In this case report, we discussed a 49 year-old female patient whose retrosternal ectopic thyroid tissue was detected by thyroid scintigraphy taken in postoperative period after total thyroidectomy performed with diagnosis of multinodular goiter. Papillary carcinoma was determined by the histopathological examination. Ectopic thyroid tissue was removed by performing sternotomy. We did not observe any postoperative surgical complications. 100 mCi dose of radioactive iodine was administered to the patient. Retrosternal ectopic thyroid tissue detected after total thyroidectomy is a rarely encountered condition. Therefore, retrosternal ectopic thyroid tissue existence should be definitely kept in mind in patients with no increase in thyroid stimulating hormone level after total thyroidectomy.
异位甲状腺组织可在从舌至膈肌的部位被发现。最常见的异位甲状腺组织分别见于舌、下颌下区域、颈部淋巴结、喉、气管、食管、纵隔、膈肌及心脏。“遗忘性甲状腺肿”是一种极为罕见的疾病，定义为在全甲状腺切除术后发现的纵隔甲状腺肿块。在本病例报告中，我们讨论了一名49岁女性患者，其在因多结节性甲状腺肿行全甲状腺切除术后的随访期甲状腺闪烁扫描检查发现胸骨后异位甲状腺组织。经组织病理学检查确诊为乳头状癌。通过胸骨切开术切除了异位甲状腺组织。我们未观察到任何术后手术并发症。给患者给予了100 mCi剂量的放射性碘。全甲状腺切除术后发现胸骨后异位甲状腺组织是一种罕见情况。因此，对于全甲状腺切除术后促甲状腺激素水平未升高的患者，应务必牢记存在胸骨后异位甲状腺组织的可能性。
