【摘要】 目的探讨彩色多普勒超声检查在肾嗜酸细胞腺瘤诊断及鉴别诊断中的应用价值。方法回顾性分析经手术病理证实的14例肾嗜酸细胞腺瘤患者的二维声像图像及彩色多普勒血流显像特点,从病灶的大小、边界、内部回声、血供情况等指标做综合分析。结果 14例肾嗜酸细胞瘤均为单发病灶,8例位于右肾,6例位于左肾。病灶长径1.9~11.4 cm,平均6.7 cm。边界清晰,形态规则,呈中等略强回声11例(78.57%),等回声或略低回声3例(21.43%),声像图中2例中央可见放射状低回声区,而病理标本中5例显示星状瘢痕。CDFI:9例瘤体周边和内部探及点条状血流信号。结论肾嗜酸细胞瘤特征性声像图表现为回声均匀略强回声包块,中央可见放射状低回声区,超声检查对其诊断与鉴别诊断具有一定临床意义。更多还原

【Abstract】 Objective To explore the value of color Doppler ultrasound in diagnosis and differential diagnosis of renal oncocytoma.Methods Ultrasonic imaging characteristics under 2D and CDFI of 14 cases of renal oncocytoma confirmed by operation and pathology were analyzed retrospectively.They have been synthetically analyzed through volume.margin,internal echo and blood flow et al.Results All of those 14 cases were single and unilateral,8 cases located in right kidney and 6 cases located in left kidney.The size of masses ranged from 1.9~11.4 cm in diameter(mean diameter 6.7 cm).All masses showed well defined and regular shape.Contrasted to renal cortex,11(78.57%) were hyperechoic and 3(21.43%) were isoechoic or hypoechoic.In 2 cases a well-defined radial hypoechoic area was seen in ultrasonic images and confirmed pathologically.In 3 cases,a central scar was identified pathologically,but not seen in ultrasonic images.CDFI:Peripheral and internal blood flow were seen in 9 masses.Conclusions The characteristic imaging features of renal oncocytoma were homogeneous hyperechoic mass especially with a central radial hypoechoic area.Ultrasound plays an important role in diagnosis of renal oncocytoma.更多还原
