超声检查对甲状腺微小乳头状癌的诊断价值

Ultrasonographic va lue in diagnosing of papillary throid microcarcinoma

目的通过对28例甲状腺微小乳头状癌患者的术前超声表现进行回顾性分析,探讨甲状腺微小乳头状癌的二维声像图和彩色多普勒特征。方法观察结节的超声表现,包括内部回声、有无钙化及钙化的特点、边界、形状、血流信号、有无侵犯被膜及颈部淋巴结转移等。结果 9例单发结节具有典型的甲状腺癌超声图像特征;4例单发结节仅表现为边界清,形态尚规则,低回声,内部回声均匀,血流稀少;15例多发结节中5例仅表现为边界清,形态规则,中等或偏低回声,8例内部可见微小钙化灶,血流较丰富,2例内部可见粗大或弧形的钙化灶。结论高频超声具有准确、实时、方便、价格低廉,尤其适用于随访观察,超声检查对甲状腺微小乳头状癌具有重要的诊断价值。

Objective To investigate the two-dimensiona ultrasound and color doppler features of papillary throid microcarcinoma. Retrospective analysis was carried out in twenty-eight patient with papillary throid microcarcinoma by analyzing the preoperative ultrasound image. Methods Ultrasound manifestations were observed in the nodula, including internal echo, calcification, boundary, shape, blood supply, ihwision adjacent capsule of thyroid or not and cervical lymph nodula metastasis, etc. Results Among twenty-eight patient, nine cases with solitary nodule presented with typical ultrasound manifestations of throid carcinoma, four cases with solitary nodule showed regular shape, hypoechoic, homogeneous echo, hypovascularity. Five cases among fifteen with multi-nodula showed clear define, regular shape, equal echo or hypoecho, eight cases had internal microcalcification and hypervascularity, and two cases had internal massive or arch calcification. Conclusion High-frequency ultrasound has accuracy, realtime, convenience and low price, especially suitable to follow up, which shows great value in the diagnosis of throid papillary microcarcinoma.
