中文摘要：

观察小儿腹部占位病变的超声表现并研究其诊断价值。选取我科诊断并经临床手术病理确诊210例腹部占位病变进行回顾性分析。本组96例良性，114例恶性。腹部良性肿瘤大多为囊性肿物声像，边界清晰且包膜完整；而实体性肿瘤多数为恶性肿瘤，多为形状不规则，回声紊乱，边界不清且向周围浸润。VEDV、VPSV、RI及PI等参数，良性肿瘤与恶性肿瘤差异有统计学意义（P〈0．05）。超声对小儿腹部肿瘤的诊断有重要意义，在临床诊断决策中起到重要的作用。

英文摘要：

The article is to observe the sonographic findings of pediatric abdominal space-occupying lesions and study its diagnostic value. 210 cases which are diagnosed in our department and clinical surgical pathology confirmed of abdominal tumor were retrospectively analyzed with 96 cases of benign, 114 cases of malignant. Abdominal benign tumors are mostly cystic neoplasm audio-visual, with clear boundary and capsular complete. Substantial tumor are most likely to be the malignant tumor. They are more irregular in shape, echo is disorder, boundary is not clear and the surrounding infiltration. VEDV, VPSV, RI and PI parameters, such as benign tumors and malignant tumors have significant difference （P〈0.05）. Ultrasound has important significance to the diagnosis of pediatric abdominal tumor, and plays an important role in the clinical diagnosis decision-making.
