摘要/Abstract

摘要： 目的探讨不同类型肾脏占位病变的超声造影特点。方法对照病理诊断结果分析76例肾脏占位病变Sono Vue超声造影特征。结果肾恶性肿瘤62例,良性肿瘤14例。肾恶性肿瘤超声造影剂的充盈和消退呈多样性,以同步增强和快增强多见,造影剂的快速消退和缓慢消退之间无明显差别,差异无统计学意义(P>0.05)。恶性肿瘤典型的表现是整个病灶弥漫增强,轮廓边界清晰,呈"亮球"征(95.2%),并多有假包膜(87.1%)。肾错构瘤表现为无假包膜的不均匀增强,而肾囊肿始终无增强。结论超声造影有助于肾占位病变的鉴别诊断和预后判断。

Abstract: Objective To study the importance of contrast-enhanced ultrasound(CEU) in the differential diagnosis of local renal space occupying lesons. Methods Seventy-six cases of renal space occupying lesions were examined by contrast-enhanced ultrasound. All patients received surgery. The characteristics of renal space occupying lesions in CEU were observed and analyzed. Results Satisfactory and dynamic-enhanced perfusion images were obtained for 76 patients. Among them, 62 lesions were diagnosed as malignant and 14 lesions as benign tumor by pathology. The way of contrast medium wash in and wash out was various. Most cases showed synchronous wash in and fast wash in(P<0.05). There was no difference between fast wash out and low wash out. A special characteristic of the malignant renal lesions was that they were rich in blood supply, tending to look like a "bright ball". Hamartoma showed asymmetric enhancement without pseudocapsule. There was no enhancement found in cases of cysts. Conclusion The contrast-enhanced ultrasound(CEU) is a useful method for differentiating renal space occupying lesions.

Key words: renal tumor, renal space occupying lesion, contrast-enhanced ultrasound
