| 目的 探讨肾嗜酸细胞瘤(RO)的声像图特征。方法 回顾性分析手术病理证实的12例RO患者的超声表现,包括病变大小、边界、形态、回声水平及血流特点。结果 12例RO患者中,超声准确定位所有病灶,其中3例误诊为肾癌,9例未能做出定性诊断。超声发现8.33%RO有中央星状瘢痕,66.67%回声均匀、75.00%边界清晰、91.67%形态规则和58.33%为等回声,66.67%肿瘤周边见环绕血流,50.00%内部多血供,且呈轮辐状分布,41.67%少血供,8.33%无血供。结论 超声对RO定性诊断较困难,但对内部回声均匀、界清、血流轮辐状分布、尤其有中央星状瘢痕的肾实性肿物,应考虑RO可能。 |

| Objective To investigate the ultrasonographic manifestation of renal oncocytoma. Methods The sonographic appearances of 12 patients with pathologically confirmed RO were retrospectively reviewed, and the size, margin, configuration, echogenicity and blood flow distribution of the lesions were analyzed. Results All of the 12 RO were detected and located correctly, among which 3 cases were misdiagnosed as renal cell carcinoma and 9 cases were not qualitatively diagnosed with ultrasound. The lesions manifested as central stellate scar in 8.33%, homogeneous enchogenicity in 66.67%, well-defined in 75.00%, regular-shape in 91.67% and isoechoic in 58.33%. Among these lesions, 6 (50.00%) were hypervascular with spoke-wheel distribution, 5 (41.67%) were hypovascular, and 1 (8.33%) was avascular, while peripheral blood flow were seen in 7 lesions (66.67%). Conclusion The diagnostic ability of ultrasound for RO is limited, but a homogeneous, well-defined solid lesion with spoke-wheel distribution of blood flow, especially with a stellate scar may suggest RO. |
