Ectopic thyroid tissue is an uncommon congenital aberration. It is extremely rare to have three ectopic foci at three different sites. The thyroid scan has been used successfully to diagnose ectopic thyroid tissue. We report a case of ectopic thyroid tissue at base of tongue, another at the level of hyoid and third one as aberrant tissue at suprahyoid location in a 16 year old female who presented with swelling in front of neck. This patient was clinically diagnosed as thyroglossal cyst and was being planned for surgery. Preoperative thyroid scan helped in establishing diagnosis of ectopic thyroid which was the only functioning thyroid tissue. Thus, it prevented unnecessary surgery. Therefore it is suggested that thyroid scan and USG/CT scan must be done as routine work up in neck swellings pre operatively to avoid unnecessary surgeries.
异位甲状腺组织是一种罕见的先天性异常。在三个不同部位出现三个异位病灶极为罕见。甲状腺扫描已成功用于诊断异位甲状腺组织。我们报告一例16岁女性病例，其舌根部有异位甲状腺组织，另一处位于舌骨水平，第三处为舌骨上位置的异常组织，该患者因颈部前方肿胀就诊。该患者临床诊断为甲状舌管囊肿，计划进行手术。术前甲状腺扫描有助于确诊异位甲状腺，而这是唯一具有功能的甲状腺组织。因此，避免了不必要的手术。所以建议在术前对颈部肿胀患者常规进行甲状腺扫描及超声/CT扫描，以避免不必要的手术。
