目的评估多排螺旋CT(MSCT)诊断甲状腺乳头状癌(PTC)伴颈淋巴结转移的临床价值。方法回顾性分析38例PTC行功能性颈清扫的术前MSCT结果,并与手术后病理诊断结果对比。结果 38例患者MSCT检查阳性率为84.2%(32/38),且绝大多数淋巴结转移灶有特征性影像学改变。颈中央区淋巴结转移率最高,达52.6%(20/38),但该区小的转移淋巴结MSCT难以检出,而致6例假阴性。结论 MSCT诊断PTC颈淋巴结转移具有较高的准确率。PTC初次手术建议常规行颈中央区淋巴结清扫。
Objective To evaluate the clinical value of multislice spiral CT (MSCT) in the diagnosis of papillary thyroid carcinoma (PTC) with cervical lymph node metastasis. Methods The preoperative MSCT results of 38 patients with functional neck dissection were retrospectively analyzed and compared with the postoperative pathological diagnosis results. Results The positive rate of MSCT in 38 patients was 84.2% (32/38), and the majority of lymph node metastases had characteristic imaging changes. Central neck lymph node metastasis rate was the highest, reaching 52.6% (20/38), but the small lymph node metastasis in this area is difficult to detect MSCT, resulting in 6 cases of false negative. Conclusion MSCT diagnosis of PTC cervical lymph node metastasis with high accuracy. PTC primary surgery recommended conventional cervical central lymph node dissection.
