【摘要】：目的总结甲状舌管囊肿(TDC)的声像图特征,探讨超声对TDC及甲状舌管癌(TDCa)的诊断价值。方法回顾性总结经病理证实的199例甲状舌管病变患者的超声资料,分析甲状舌管良恶性病变的声像图特征并进行分型。结果甲状舌管病变超声均表现为舌根与胸骨上窝之间的囊性包块,可分为四型:典型囊肿型175例,部分内可见带状分隔,后方回声增强,CDFI示囊内未见血流信号;混合回声型21例,壁厚毛糙,周围软组织回声增强,CDFI示壁上及周边血流信号增多;瘘管型2例,于囊肿深面走行一条细长迂曲的无回声窦道延伸至舌骨后方;囊肿恶变型1例,囊壁上见高回声结节并内簇状分布的点状钙化,伴颈部淋巴结转移并向周边组织侵犯,CDFI示结节内可见血流信号。结论超声可以清晰显示TDC及瘘管形成等特殊表现,是诊断TDC的首选方法,认识不同的声像图表现有助于鉴别TDC和TDCa。
[Abstract]:Objective to summarize the sonographic features of thyroglossal duct cyst (TDC) and to evaluate the value of ultrasonography in the diagnosis of TDC and TDCa.Methods the ultrasonographic data of 199 patients with thyroglossal duct lesions confirmed by pathology were retrospectively summarized and the sonographic features of benign and malignant lesions of thyroid tongue duct were analyzed and classified.Results the lesions of the thyroglossal duct showed cystic mass between the base of tongue and the suprasternal fossa, which could be divided into four types: 175 cases of typical cyst type, with partial banded septum, and no blood flow signal was found in the cyst with enhanced posterior echo CDFI.Mixed echo type (21 cases) with coarse wall and enhanced peripheral soft tissue echo CDFI showed increased blood flow signals on the wall and around the wall, fistula type in 2 cases, with a slender, tortuous anechoic sinus extending to the back of hyoid bone, cyst malignant type in 1 case.Hyperechoic nodules with cluster calcification were seen on the wall of the cyst with lymph node metastasis in the neck and invasion of the peripheral tissue with CDFI to show that blood flow signal could be seen in the nodules.Conclusion Ultrasound can clearly display TDC and fistula formation, and is the first choice in the diagnosis of TDC. It is helpful to distinguish TDC from TDCa by recognizing different sonographic manifestations.
