| 目的 探讨超声造影诊断囊性肾癌的价值。 方法 收集2009年4月-2013年12月经手术病理证实为囊性肾癌的患者28例（28个病灶），分析二维超声及超声造影表现。二维超声主要观察囊性肿块的大小、形态、边界、内部回声，血流情况。超声造影主要观察囊性肿块囊壁、分隔及实性成分的增强表现，主要指标：增强模式、增强程度及假包膜征。结果 本组28个囊性肿块包括多房性囊性肾癌16个，透明细胞癌出血、坏死及囊性变12个。二维超声显示囊实性肿块18个，多房囊性肿块8个，未见分隔及实性成分肿块2个；CDFI示20个肿块内部可见血流信号，8个未见血流信号，CDFI血流显示率为71.43%（20/28）。超声造影示全部肿块内囊壁、分隔及实性成分均见造影剂增强，超声造影血流显示率为100%。超声造影增强模式：15个肿块表现为“快进慢退”，7个表现为“快进快退”，6个表现为“等进等退”；增强程度：16个肿块呈高增强，12个呈中等增强；假包膜征：6个肿块可见假包膜征，22个未见假包膜征。结论 超声造影在显示囊性肾癌内低速血流及微循环血供情况，其敏感度优于二维超声。 |

| Objective To expolre the value of contrast-enhanced ultrasound in diagnosis of cystic renal cancer. Methods Totally 28 patients (28 lesions) with cystic renal cancer confirmed by surgery pathology were enrolled in April 2009 to December 2009, and characteristics of two-dimensional ultrasound and contrast-enhanced ultrasound were analyzed retrospectively. Cystic masses of the size, shape, border, internal echo and blood flow were mainly observed in two-dimensional ultrasound. Cystic masses capsule wall, space and enhancement of the solid component performance were mainly observed in contrast-enhanced ultrasound. The indicators included enhancement pattern, increasing the extent and pseudocapsule. Results Pathology showed multilocular cystic kidney cancer in 16 lesions, and clear cell carcinoma, hemorrhage, necrosis in 12 lesions. Two-dimensional ultrasound showed cystic or solid mass in 18 lesions, multilocular cystic mass in 8 lesions, no separation and solid mass in 2 lesions; CDFI showed 20 lesions (20/28, 71.43%) with internal blood flow signal and 8 lesions no blood flow signal. Contrast-enhanced ultrasound showed "fast in and slow out" in 15 lesions, "fast in and fast out" in 7 lesions, "identical in and identical out" in 6 lesions. Sixteen lesions were hyperenhancement, 12 lesions were isoenhancement. Totally 6 lesions had pseudocapsule and 22 lesions without pseudocapsule. Conclusion Contrast-enhanced ultrasound shows cystic renal cancer in low speed blood flow and microcirculation blood supply situation, the sensitivity is better than that of two-dimensional ultrasound. |
