Abstract

Ectopic thyroid tissue (ETT) refers to the presence of thyroid tissue in locations other than the normal anterior neck region between the second and fourth tracheal cartilages. Multiple ectopia of the thyroid is extremely rare. Here we report a case of 10-year-old girl with anterior midline neck swelling and hypothyroidism with dual ectopia of thyroid gland without orthotopic thyroid gland. Planar 99 m-technetium pertechnatate scan identified ETT corresponding to the palpable neck swelling. Single photon emission computed tomography/computed tomography (SPECT/CT) demonstrated ETT in two locations, one corresponding to the palpable mass and another in the in the sublingual location. This case thus demonstrates the important role of hybrid SPECT/CT in the identification of dual ectopia along the thyroglossal tract.

摘要

异位甲状腺组织（ETT）是指甲状腺组织出现在正常颈部前方第二至第四气管软骨之间区域以外的部位。甲状腺多处异位极为罕见。在此，我们报告一例10岁女孩，其颈部前正中线肿胀且伴有甲状腺功能减退，甲状腺呈双异位且无原位甲状腺。平面99m锝高锝酸盐扫描确定了与可触及的颈部肿胀相对应的异位甲状腺组织。单光子发射计算机断层扫描/计算机断层扫描（SPECT/CT）显示在两个部位存在异位甲状腺组织，一个对应于可触及的肿块，另一个位于舌下部位。因此，该病例证明了混合SPECT/CT在识别沿甲状舌管的双异位中的重要作用。
