摘　　要：目的探讨甲状舌管癌(TDCa)的CT影像学表现,提高对该肿瘤的认识。方法回顾分析11例经手术病理证实的TDCa的CT平扫及增强图像,并复习相关文献,总结影像学特征。结果11例TDCa均表现为颈前中线区肿块,边界欠清,8例位于舌骨下方水平,3例位于舌骨水平。11例病灶内均见实质性软组织成分,9例伴微钙化灶。10例病灶呈囊实性肿块,增强扫描囊壁及附壁结节中等-明显强化。1例病灶呈实性肿块,侵袭破坏舌骨,增强扫描明显强化。1例伴双侧颈部肿大淋巴结,病理证实为淋巴结转移。结论CT发现颈前中线区肿块伴有如囊性病灶内出现实性附壁结节、囊壁或内部分隔增厚、微钙化灶、舌骨侵袭性破坏或颈部肿大淋巴结影像学特征,应考虑TDCa的诊断。Objective To describe the CT imaging findings of thyroglossal duct carcinoma(TDCa)and to improve the understanding of this tumor.Methods The CT plain and enhanced images of 11 cases with histopathologically proved TDCa were retrospectively analyzed,and the related literatures were reviewed,and then the imaging characteristics were summarized.Results All eleven TDCa cases presented as a mass in the anterior midline area of the neck with poorly defined boundaries,eight cases were located below the level of hyoid bone and three cases were located at the level of hyoid bone.Solid soft tissue components were found in all lesions,of which nine cases were accompanied by microcalcifications.The lesions in 10 cases were cystic-solid masses with moderate to obvious enhancement of the cyst wall and mural nodules.In one case,the lesion was a solid mass with obvious enhancement,which destroyed the hyoid bone.One case was accompanied by bilateral enlarged lymph nodes in the neck,which was confirmed by pathology as metastatic cancer.Conclusion CT findings in the anterior midline area of the neck with the following imaging features,such as solid mural nodules within cystic lesions,thickening of cyst wall or internal septum,microcalcifications,invasive destruction of the hyoid bone or enlarged lymph nodes in the neck,the diagnosis of TDCa should be considered.
