摘要: 报道1例17岁女性舌骨前异位甲状腺癌患者，因发现颈前肿物1周余入院。体检见颈前舌骨平面一3 cm×2 cm大小肿物。彩超探及一囊实性混合回声团块，内见点状强回声。CT提示舌骨前囊实性病灶，内见点状致密钙化影。误诊为甲状舌管囊肿，行手术治疗，术后病理诊断为甲状腺乳头状癌伴囊肿形成。Abstract: A clinical case of ectopic thyroid carcinoma in front of hyoid bone was reported in this paper. The patient, a 17-year-old female, presented with an enlarging neck mass of 1-week history. Physical examination revealed a 3 cm×2 cm neck mass in front of the hyoid bone. Ultrasonographic depicted as a cystic solid mixed echogenic mass with punctate strong echogenicity. CT scan showed a cystic-solid mass in front of the hyoid bone with punctate calcifications. The patient was misdiagnosed as a thyroglossal duct cyst and underwent surgery. The final pathological diagnosis was papillary thyroid carcinoma with cyst formation.
