目的探讨超声诊断老年人阑尾黏液性肿瘤的价值. 方法依据手术病理结果回顾性分析11例老年人阑尾黏液性肿瘤和15例非老年人阑尾黏液性肿瘤的声像图特点. 结果两组患者二维声像图表现可分为3型:(1)右下腹囊性肿物,透声好;(2)右下腹囊性肿物、内透声差;(3)右下腹囊实性肿物.声像图特征:(1)右下腹肿物横径多大于2 cm;(2)形态较规则,腊肠形或近椭圆形;(3)边界清晰、边缘光滑;(4)内部多为无回声或囊性为主混合回声,部分呈“洋葱皮”征;(5)血流不丰富、稀少,部分壁内可见点条状血流.两组患者超声分型、声像图特点和术前超声诊断率差异无统计学意义(P＞0.05). 结论超声作为方便易行首诊影像学方法,在患者右下腹发现横径大于2cm囊性或囊实性肿物时,超声医师要意识到阑尾黏液性肿瘤可能,及时提示避免误诊.

Objective To the value of ultrasonic imaging in diagnosis of appendiceal mucinous neoplasms in patients.Methods A retrospective review was performed for the 26 cases undergoing pre-operative ultrasonography and finally diagnosed as appendiceal mucinous neoplasms by pathology.The 26 patients were included in the study,11 elderly patients aged ≥60 years as group A,and 15 younger patients aged ＜ 60 years as group B.The characteristics of the ultrasonic imaging were analyzed.Results Features of ultrasound images leading to diagnosis were summarized as following.The lesion transverse diameter was over 2 cm,with anechoic or hypoechoic area of lesion or "onion skin" sign inside the lesions.There were distinct borderlines between lesions and surrounding tissues,with no or little blood in the color doppler flow imaging.Conclusions There are same u1trasonography characteristics of appendiceal mucinous neoplasms in two age groups.Improving the knowledge of this disease and grasping the clinical and sonography characteristics are stringent to enhance the accuracy rate of diagnosis.
