| 目的 探讨低回声为主型肾血管平滑肌脂肪瘤常规超声与超声造影(CEUS)特征。方法 经手术病理证实的11例低回声为主型肾血管平滑肌脂肪瘤患者,均接受常规超声及CEUS,并分析其影像学特征。结果 11例均经手术病理证实为少脂肪或乏脂肪肾血管平滑肌脂肪瘤,其中9例为经典型肾血管平滑肌脂肪瘤,2例为潜在恶性的上皮样血管平滑肌脂肪瘤。常规超声示11例肿块均以低回声为主,肿块内部或周边可见散在点状及小片状高回声;彩色多普勒示2例为富血供肿块,2例为少血供肿块,7例为乏血供肿块。CEUS示3例为"快进快出"型(3/11, 27.27%),8例为"快进慢出"型(8/11,72.73%);7例为边缘型增强(7/11,63.64%),1例为中央型增强(1/11,9.09%),3例为同步增强(3/11,27.27%)。结论 低回声为主型肾血管平滑肌脂肪瘤为少见型肾肿瘤,常规超声结合CEUS有助于诊断和鉴别诊断。 |

| Objective To explore the features of hypoechoic renal angiomyolipoma (RAML) with conventional ultrasound and contrast-enhanced ultrasound (CEUS). Methods Eleven patients confirmed sequentially with operation and pathology underwent conventional ultrasonography and CEUS, and the imaging characteristics were analyzed. Results Totally 11 patients were demonstrated as RAML with no or a minimal amount of fat tissue, including 9 classical RAML and 2 epithelioid RAML with potentially aggressive. All 11 patients showed hypoechoic primarily, with less hyperecho in periphery and interior of the tumors in conventional ultrasound, 2 were hypervascular, 2 were hypovascular and 7 were avascularity in color Doppler ultrasound. During CEUS, fast wash-in and fast wash-out (3/11, 27.27%) was detected in 3 tumors, and fast wash-in and slowly wash-out in 8 (8/11, 72.73%), with enhancement first happened on peripheral, then in the center area in 7 (7/11, 63.64%), first happened in the center, then on peripheral area in 1 tumor (1/11, 9.09%), simultaneously on peripheral and center area in 3 tumors (3/11, 27.27%). Conclusion The hypoechoic RAML is a rare kind of renal tumor.Conventional ultrasound combining with CEUS are significant in diagnosis and differential diagnosis of this tumor. |
