摘要
目的探讨超声造影对肾脏占位病变的诊断价值,提高其诊断及鉴别诊断水平。方法对35例经穿刺或手术病理结果证实为肾脏占位病变患者的超声造影表现进行回顾分析,观察其增强程度、增强均匀度、假包膜征、增强、消退时间及增强方式。结果超声造影示恶性肿瘤28例,良性病变7例。恶性肿瘤中肾癌17例,肾盂癌11例;良性病变中肾血管平滑肌脂肪瘤4例,肾囊肿3例。肾癌多表现为快进快出、弥漫性不均匀性明显增强及假包膜形成;肾盂癌多表现为慢进快出和弥漫性均匀性不明显增强;肾血管平滑肌脂肪多表现为快进慢出和向心性均匀性不明显增强;肾囊肿多表现为无增强。结论超声造影对肾脏占位病变的诊断和良恶性病变的鉴别诊断有较高价值。
Objective To explore the diagnostic value of contrast - enhanced ultrasound （CEUS） in renal occuping lesions so as to improve the diagnosis and differential diagnosis level. Methods CEUS features of renal occuping lesions confirmed by pathology in 35 patients were retrospectively analyzed in combination with literature review. The enhancement degree, the homogeneity of enhancement, the pseudocapsule, the washing - in and washing - out time and the enhancement pattern were observed. Results CEUS showed there were 28 cases of malignant tumor,and 7 cases of benign lesions. Malignant tumors including 17 cases of renal cell carcinoma and 11 cases of renal pelvic carcinoma, benign lesions including 4 cases of renal angiomyolipoma and 3 cases of renal cysts. Most of renal cell carcinoma showed fast wash - in and fast wash - out, obviously heterogeneous diffuse enhancement and pseudocapsule formation. Most of renal pelvic carcinoma showed slow wash - in and fast wash - out, obviously homogeneous diffuse enhancement. Most of renal angiomyolipoma displayed fast wash - in and slow wash- out, centripetal enhacement, homogeneous and obvious enhacement. No enhancement was found in renal cysts. Conclusion CEUS has high value in diagnosis of renal occuping lesions and differential diagnosis of benign and malignant lesions.
