An ectopic thyroid gland results from the abnormal migration of the thyroid in the course of its development. Primary ectopic mediastinal thyroid is very rare and occurs in less than 1% of all goiters that can be surgically excised. Ectopic thyroid tissue has a characteristic sonographic appearance as smooth-bordered, homogeneous, hypoechoic tissue with fine specular echoes. We report 3 cases of mediastinal ectopic thyroid diagnosed by endobronchial ultrasound-guided transbrochial needle aspiration biopsy.
异位甲状腺是甲状腺在发育过程中异常迁移所致。原发性纵隔异位甲状腺非常罕见，在所有可手术切除的甲状腺肿中发生率不到1%。异位甲状腺组织具有特征性超声表现，为边界光滑、均匀、低回声且有细小镜面回声的组织。我们报告3例经支气管内超声引导下经支气管针吸活检诊断的纵隔异位甲状腺病例。
