摘　　要：目的分析青年乳头状甲状腺癌患者MSCT影像学表现及其与颈部淋巴结转移的相关性。方法回顾分析本院2017年6月至2019年9月收治的116例乳头状甲状腺癌患者作为研究对象,所有患者均进行MSCT检查后根据颈部淋巴结有无转移分为转移组(86例)和未转移组(30例)。通过所得MSCT图像了解乳头状甲状腺癌患者颈部淋巴结转移者与未转移者MSCT影像学表现差异,进一步分析其MSCT影像学表现与颈部淋巴结转移的相关性。结果乳头状甲状腺癌患者淋巴结转移者与未转移者在肿瘤直径、钙化、坏死、周围侵犯、强化特征CT征象上比较差异有统计学意义(P<0.05),淋巴结转移患者肿瘤直径多≥2cm,肿瘤内部多见钙化、坏死、周围侵犯现象,分别占76.74%(66/86)、77.80%(67/86)、87.20%(76/86),强化特点以重度强化为主,占94.18%(81/86);淋巴结为转移患者肿瘤直径常≥2cm,肿瘤内部有钙化、坏死、周围侵犯情况,但明显低于淋巴结转移组,53.33%为轻、中度强化。结论在乳头状甲状腺癌患者术前诊断中,如患者肿瘤直径≥2cm,重度强化且有坏死、钙化、周围侵犯等CT征象时,需高度怀疑存在淋巴结转移。Objective To analyze the MSCT imaging manifestations of young patients with papillary thyroid cancer and its correlation with cervical lymph node metastasis.Methods 116 patients with papillary thyroid cancer treated in our hospital from June 2017 to September 2019 were retrospectively analyzed.All patients were divided into metastatic group(86),and non-metastatic group(30)According to the presence or absence of cervical lymph node metastasis after MSCT.The MSCT images were used to analyze the differences in MSCT imaging between patients with papillary thyroid cancer and cervical lymph node metastasis and patients with papillary thyroid cancer without cervical lymph node metastasis.The correlation between the MSCT imaging manifestations,and cervical lymph node metastasis was further analyzed.Results There were significant differences in CT signs such as tumor diameter,calcification,necrosis,peripheral invasion,and enhanced features in patients with cervical lymph node metastasis and patients without cervical lymph node metastasis(P<0.05).The tumor diameter of patients with lymph node metastasis was≥2cm,and calcification,necrosis,and peripheral invasion were common in the tumor,accounting for 76.74%(66/86),77.80%(67/86),and 87.20%(76/86).The characteristics of enhancement were mainly severe enhancement,accounting for 94.18%(81/86).Tumor diameter of patients with lymph node metastasis was often≥2cm.There were calcification,necrosis and surrounding invasion in the tumor,but it was significantly lower than that in the lymph node metastasis group.53.33%were mild and moderately enhanced.Conclusion In the preoperative diagnosis of patients with papillary thyroid cancer,if the patient's tumor diameter was≥2cm,and there are CT signs such as severe enhancement and necrosis,calcification,and peripheral invasion,it is highly suspected that lymph node metastasis exists.
