Dual Ectopy of Thyroid Tissue: Intratracheal and in Nasopharynx, Associated with Normally Located Thyroid

Dual ectopic thyroid tissue associated with normally located thyroid, is a rare anomaly. We report a case of 42 years lady, who underwent left hemithyroidectomy for nodules in the left lobe of thyroid 15 years back. She presented with right side neck swelling and dyspnea for 6 months. Right hemithyroidectomy was done for multinodular goiter involving right lobe of thyroid. She developed stridor on the first postoperative day. CT scan and MRI showed intratracheal ectopic thyroid tissue. Ectopic thyroid tissue was removed by dividing cricoid cartilage, and trachea was repaired. Radio iodine scan after 6 weeks showed another ectopic thyroid tissue in nasopharynx. Patient refused for radio iodine ablation and, she was given thyroxin replacement.
