目的探讨肾错构瘤的彩色多普勒超声诊断及分型。方法对53例肾错构瘤行彩色多普勒超声检查,其中24例经手术病理证实,29例随访2~5年后证实。结果根据肾错构瘤二维声像图与瘤体内血流情况将肾错构瘤可分成三型:1)单纯型42例,占79%(42/53);瘤体均呈高回声光团;2)伴出血型10例,占19%(10/53);瘤体呈混合性团块,内为高回声光团伴液性暗区;3)瘤体内伴假性动脉瘤型1例,占2%(1/53);瘤体二维声像图与伴出血型相同,CDFI瘤体液性暗区内见典型红蓝往返假性动脉瘤之涡流。结论彩色多普勒超声诊断在肾错构瘤诊断、分型中具有重要意义。
Objective To investigate the color Doppler ultrasound diagnosis and classification of renal hamartoma. Methods Fifty-three cases of renal hamartoma were examined by color Doppler ultrasonography, of which 24 cases were confirmed by surgery and pathology, and 29 cases were followed up for 2 to 5 years. Results Renal hamartoma could be divided into three types according to the two-dimensional sonography of renal hamartoma and blood flow in the tumor: 1) 42 cases (79%, 42/53) 2) with hemorrhage in 10 cases, accounting for 19% (10/53); tumor was mixed mass, which was hyperechoic light with liquid dark area; 3) tumor with pseudoaneurysm Type 1, accounting for 2% (1/53); tumor two-dimensional sonography and hemorrhagic same type, CDFI tumor liquid dark area see the typical red and blue back and forth pseudoaneurysm of the vortex. Conclusion The color Doppler ultrasound diagnosis is of great significance in the diagnosis and classification of renal hamartoma.
