目的探讨肾淋巴瘤的声像学特点,并与肾癌、肾错构瘤进行比较。方法回顾性分析2010-2013年在我院确诊为肾淋巴瘤患者9例13个病灶、肾透明细胞癌患者14例14个病灶、肾错构瘤患者13例16个病灶的声像图表现。结果 3/9例肾淋巴瘤为双侧多发病灶,与肾癌仅见单肾发生有差异(P=0.047);肾淋巴瘤与肾错构瘤病灶主体(P=0.025)、与肾癌血供(P=0.006)有差异;肾淋巴瘤与肾癌和肾错构瘤的病灶形态、回声、腹膜后肿大淋巴结分别有统计学差异(P=0.004,P=0.006;P=0.000,P=0.000;P=0.017,P=0.014)。结论肾淋巴瘤与肾癌、肾错构瘤声像图表现有所差异,加强认识,可提高超声的鉴别诊断能力。
Objective To investigate the sonographic features of renal lymphoma and to compare with renal carcinoma and renal hamartoma. Methods We retrospectively analyzed the sonographic findings of 13 lesions in 9 patients with renal lymphoma and 14 lesions in 14 patients with renal clear cell carcinoma and 13 lesions in renal hamartoma from 2010 to 2013 in our hospital. Results Three to nine cases of renal lymphoma were bilateral multiple lesions, which were different from renal carcinoma (P = 0.047). Renal lymphoma and renal hamartoma (P = 0.025) (P = 0.006). There was a significant difference in the morphology, echogenicity, and retroperitoneal lymph node between renal lymphoma and renal carcinoma and renal hamartoma (P = 0.004, P = 0.006, P = 0.000, P = 0.000; P = 0.017, P = 0.014). Conclusion Renal lymphoma and renal cell carcinoma and renal hamartoma have different acoustic maps, to enhance awareness, can improve the differential diagnosis of ultrasound.
