目的探讨阑尾黏液性肿瘤(AMN)的临床和超声表现及良恶性鉴别的特征。方法对24例经手术病理证实的AMN患者的临床和超声资料进行回顾性分析。结果 AMN声像图特征为阑尾明显增粗,阑尾壁多增厚,内壁可伴钙化或结节;临床特征为血常规白细胞计数(WBC)多数正常,癌胚抗原(CEA)可增高;内壁伴结节特征在良恶性间差异有统计学意义(P<0.05)。结论 AMN超声表现有一定的特征性,超声发现内壁伴结节时提示恶性。
Objective To investigate the clinical and ultrasonographic features of benign and malignant appendix mucinous neoplasms (AMN). Methods The clinical and ultrasonographic data of 24 patients with AMN confirmed by surgery and pathology were retrospectively analyzed. Results The features of AMN were obvious thickening of appendix, thickening of appendix wall, inner wall may be associated with calcification or nodules; clinical features of the blood for the majority of normal white blood cell count (WBC), carcinoembryonic antigen (CEA) can be increased; The characteristics of nodules had a significant difference between benign and malignant (P <0.05). Conclusion AMN ultrasound has a certain characteristic of the ultrasound findings of the wall with nodular malignant.
