We provide a case report of two thyroid nodules in an 8-year-old girl, which revealed malignant ultrasonographic findings and which were confirmed as ectopic thymic tissue by total thyroidectomy. The ultrasound presentations of intrathyroidal thymus glands were similar to those of the malignant thyroid nodules. In addition, in this case, there were two ectopic thymus lesions in the thyroid gland, which undoubtedly increased the difficulty of diagnosis. The occurrence of multiple ectopic thymic lesions in the thyroid gland was different from previous reports. Therefore, clinicians should take into consideration this rare entity, and should not mistake it as a thyroid neoplasm; moreover, they should not perform extensive thyroid resection.
我们报告一例8岁女孩的两个甲状腺结节病例，其超声检查结果显示为恶性，全甲状腺切除术后证实为异位胸腺组织。甲状腺内胸腺的超声表现与恶性甲状腺结节相似。此外，该病例中甲状腺内有两个异位胸腺病变，这无疑增加了诊断难度。甲状腺内出现多个异位胸腺病变与既往报道不同。因此，临床医生应考虑到这种罕见情况，不应将其误诊为甲状腺肿瘤；此外，不应进行广泛的甲状腺切除术。
