目的 探讨甲状腺乳头状癌的彩色超声影像学特征及其与病理学基础的相关性。方法 回顾性分析我院2014年1月至 2015年5月45例经手术切除或细针穿刺后病理明确诊断的甲状腺乳头状癌患者的资料，分析其超声影像学表现与病 理学基础的相关性。结果 45例甲状腺乳头状癌患者共50个结节超声诊断阳性率为96%（48／50)，46例(92％)表现 为低回声结节，26例（52%）表现为边界不清，31例(62％)表现为回声不均匀，20例(40％)表现为无晕环，13例 （26%）表现为晕环不完整或不规则，36例（72%）表现为纵横比>1，26例（52%）病变内部可发现斑点状或条状钙 化，30例（60%）表现为内部血流丰富或周边条状血流，3例（6%）可探及周围异常肿大淋巴结。结论 超声对甲状 腺乳头状癌具有一定诊断价值。

Objective To explore the Ultrasound imaging features and pathologic findings of papillary thyroid carcinoma. Methods The Ultrasound images of 45 cases between January 2014 year to May 2015 year with histopathology-proven papillary thyroid carcinoma were retrospectively reviewed, Analysis the pathologic basics of Ultrasound images. Results The positive rate in Ultrasound images is 96% of 45 cases with 50 tubers. 92% with low echo noeules, 52% with fuzzy boundary, 62% with irregular echo, 40% without peripheral halo ring, 26% with incomplete peripheral halo ring, 72% with a ratio>1 in longitudinal/breadth, 52% with microcalcirication in nudules, 6% with swelling lymph nodes in neck. Conclusion The Ultrasound imaging features of Papillary thyroid carcinoma are based on the pathologic findings.
