摘要
目的探讨128层螺旋CT在甲状腺乳头状癌的诊断价值。方法回顾性分析48例经手术病理证实的甲状腺乳头状癌的128层螺旋CT资料,主要对原发病灶及颈部转移淋巴结的CT表现进行分析。结果大部分PTC境界不清楚,瘤周"半岛状"瘤结节强化15例,瘤周"残圈"征17例,"晕环征"10例。合并钙化者21例,其中细颗粒状钙化11例,粗颗粒状钙化5例,混合性钙化5例。48例患者中33例发生颈部淋巴结转移,增强后淋巴结明显强化,囊性变7例,合并壁结节6例,11例病灶内见钙化,其中细颗粒状钙化6例。结论甲状腺乳头状癌CT表现有一定的特点,128层螺旋CT薄层重建及增强扫描能够更好地评价原发病灶及淋巴结转移。
Objective To assess the value of 128-slice spiral CT in the diagnosis of papillary thyroid carcinoma. Methods CT of 48 patients with histologically confirmed papillary thyroid carcinoma was reviewed. The imaging appearance of the primary neoplasm and metastatic cervical lymphadenopathy was analyzed. Results The tumor margin was often ill-defined. After intravenous contrast administration, peninsular-shaped nodules （15 patients ）, incomplete ring （17）and halo sign （10）around the tumors were visible. There were calcifications in 21 tumors including punctate （11）, granular （5）, and mixed calcifications （5）. Of 33 lymph node metastasis, cystic degeneration （7）, intracystic nodules （6）, and punctate calcifications （6）were noted in the lymph nodes. Conclusions Contrast-enhanced 128-slice CT characteristics with multi-planar reconstruction allow accurate evaluation of the primary papillary thyroid carcinoma and metastatic lymph nodes.
