Objective To improve the ultrasonic differential diagnosis of thyroid lump through analyzing pathological and ultrasonic features of papillary thyroid carcinoma. Methods Records of 173 cases papillary thyroid carcinoma were analyzed retrospectively in terms of preoperative ultrasonic manifestation, lesion size, echo,boundary, calcification, blood supply, lymph node metastasis and accompanying diseases etc. Results The avthe 173 papillary thyroid carcinoma cases, the number of cancer nodule was 203. There was no statistical difference between papillary thyroid carcinoma lesion and papillary thyroid microcarcinoma lesion in terms of low echo and ill-defined borders (P ＞ 0. 05). The former is higher than the latter in blood flow speed, microcalcification rate, and preoperative ultrasonic diagnosis rate (P ＜0. 01, P ＜0. 05, P ＜0. 01 respectively). The mulifocality rate for the 173 cases with papillary thyroid carcinoma is 33.53% (58/173). There was no statistical difference between papillary thyroid carcinoma and papillary thyroid microcarcinoma in cancer lesion(P ＞0. 05), while the former has a higher rate of lymph node metastasis than the latter(P ＜0. 01). Preoperative diagnosis rate is higher in papillary thyroid microcarcinoma cases without other thyroid diseases than in cases with other thyroid diseases (P ＜ 0. 05). No statistical difference of preoperative diagnosis rate was seen between papillary thyroid carcinoma patients with other thyroid diseases and those without other thyroid diseases (P ＞ 0. 05). Conclusions The overall evaluation of thyroid nodule diameter, boundary, echo, small calcification, lymph node metastasis, blood supply, accompanying diseases and so on can improve diagnosis of primary papillary thyroid carcinoma.
