多结节性甲状腺肿(MNG)是甲状腺的慢性良性结节肿大。它表现为前部无痛颈部肿块,可能会对气管和食道施加压力并引起压迫症状。MNG是一种常见的甲状腺疾病;然而,咽后甲状腺肿被认为是罕见的,很少报告病例。我们报告了两名患者的病例,他们向我们的机构提供了咽后延伸的MNG:一名62岁的女性患者,表现为进行性颈前肿块,颈部静脉扩张;一名49岁的男性,表现为无痛性颈前肿块。两名患者均成功进行了甲状腺全切除术,术后恢复顺利。咽后延伸的MNG的临床表现因患者而异;因此,高度怀疑是最重要的。虽然咽后延伸不会引起压迫症状,它应该引起胸骨后大量成分的怀疑。
Multinodular goiter (MNG) is a chronic benign nodular enlargement of the thyroid gland. It presents as an anterior painless neck mass, potentially progressing to exert pressure on the trachea and esophagus and giving rise to compressive symptoms. MNG is a common thyroid gland disorder; however, retropharyngeal goiter is considered rare with few reported cases. We report the cases of two patients who presented to our institution with MNG with retropharyngeal extension: a 62-year-old female patient who presented with a progressive anterior neck mass with dilated neck veins; and a 49-year-old male who presented with a painless anterior neck mass. Both patients successfully underwent total thyroidectomy with an uneventful postoperative recovery. The clinical presentation of MNG with retropharyngeal extension varies with patients; hence, a high index of suspicion is of the utmost significance. While the retropharyngeal extension does not cause compressive symptoms, it should raise the suspicion of a large retrosternal component.
