超声诊断甲状腺结节误诊原因分析

The Factors Accounting for Misdiagnosis of Thyroid Nodules by Ultrasonography

目的 :探讨超声诊断甲状腺结节的漏、误诊原因。材料和方法 :对我院 2 0 0 2年手术治疗的 10 7例甲状腺结节患者超声及病理诊断进行回顾性分析。结果 :超声诊断正确 81例 ,误诊 13例 ,漏诊 13例。漏、误诊的主要原因是多源性结节并存、部分结节声像图表现不典型、缺乏对临床资料的了解和经验不足。结论 :甲状腺结节的超声鉴别诊断价值的评价应客观。综合分析甲状腺结节的二维及彩色多谱勒超声征象并密切结合临床可以减少漏。

Purpose: The aim of this study is to analyze the factors for misdiagnosis in ultrasonographic evaluation of thyroid nodules. Materials and Methods: The pre operative diagnosis of ultrasonography in 107 patients with thyroid nodules were retrospectively reviewed in light of their pathologic results. Results: The pre operative ultrasonography correctly diagnosed 81 cases, with incorrect and false diagnosis in 13 cases each. The misdiagnosis was accounted for by several factors including multiform nodules, lack of typical ultrasound features and of clinical experience. Conclusion: It is of clinical importance to avoid the ultrasonographic misdiagnosis of thyroid nodules by combining the US characteristic and the blood supply pattern on CDFI, and the proper clinical references. The diagnostic value of ultrasonography in thyroid nodules ought to be viewed objectively.
