Abstract
Some cases of thyroid malignant tumors and thyroid lymphoma were reported to have caused tracheal stenosis and choking. Benign thyroid tumors with dyspnea due to tracheal stenosis are very rare. We experienced a benign thyroid tumor that caused tracheal stenosis and dyspnea. In the preoperative CT, there was tracheal stenosis due to enlarged bilateral thyroid lobes and the width of the stenotic lumen was 7mm. Subtotal thyroidectomy improved the dyspnea. Postoperative histopathologic examination confirmed follicular adenoma without malignant lesions or chronic thyroiditis. On postoperative CT, the tracheal stenosis had improved and the lumen had increased to 15mm. The above findings would suggest that it should be keep in mind that even benign thyroid tumors with tracheal stenosis of less than 7mm in the lumen have the possibility of causing dyspnea.
Highlights
Thyroid diseases with airway stenosis caused by cancer and lymphoma have been reported [1,2]
We previously presented that a case of a huge malignant lymphoma with chronic thyroiditis that cause dyspnea due to tracheal stenosis [3]
We present a case of a 75-year-old Japanese male patient with dyspnea due to a benign thyroid tumor
Summary
Thyroid diseases with airway stenosis caused by cancer and lymphoma have been reported [1,2]. We recently experienced a benign thyroid tumor with dyspnea due to tracheal stenosis and performed subtotal thyroidectomy. This report describes the clinical findings, imaging examination, operation and postoperative progress and some considerations by referring to various studies. Ten years ago, he suffered a traumatic injury to his upper right limb that required amputation, during which a tracheotomy was performed to secure the airway under general anesthesia. He suffered a traumatic injury to his upper right limb that required amputation, during which a tracheotomy was performed to secure the airway under general anesthesia This tracheostomy was closed after the operation. The thyroglobulin was within the normal range of 26.80ng/ml (normal range:0-33.70ng/ml)
