摘　　要：目的分析甲状腺微小乳头状癌增强CT特点及其病理基础。方法回顾性研究经病理证实为甲状腺微小乳头状癌的28例患者的CT及病理资料,对照观察原发灶强化方式、被膜受累和钙化情况以及颈部淋巴结转移灶体积和强化方式。结果病理确诊甲状腺微小乳头状癌原发灶42个,颈部淋巴结转移灶13个,CT图像识别原发灶33个(79%),转移灶6个(46%)。原发灶CT征象包括低强化33个(100%),被膜受累14个(42%),钙化8个(24%)。颈部淋巴结转移灶CT征象包括淋巴结增大5个(83%,短径≥10 mm)和强化不均3个(50%)。结论甲状腺微小乳头状癌原发灶具有低强化、常伴被膜受累、可伴钙化的CT特点,颈部淋巴结转移可表现为增大及不均质强化的结节。Objective To analyze the characteristics of enhanced CT and pathological basis in papillary thyroid microcarcinoma. Methods CT imagings and pathological data of 28 cases papillary thyroid microcarcinoma were ret- rospectively analyzed. Comparative study on CT and pathology contained enhancement pattern, membrane invasion and calcification of primary lesions and volume and enhancement pattern of metastasis lymph nodes. Results Of 42 papillary thyroid microcarcinoma lesions, 33 lesions （79%） were positive in CT. And of 13 cervical metastasis lymph nodes, 6 lesions （46%） were positive in CT. In primary lesions, 33 lesions （100%） had low degrees enhancement, 14 lesions （42%） had membrane invasion and 8 lesions （24%） had calcification. In cervical metastasis lymph nodes, 5 le- sions （83%） were enlarged and 3 lesions （50%） were inhomogenous enhancement. Conclusion The papillary thyroid microcarcinoma had low degrees enhancement always, membrane invasion often and calcification sometimes. ＇The cer- vical metastasis lymph nodes appeared as enlarged nodes with inhomogenous enhancement.
