肾嗜酸细胞腺瘤的超声诊断及鉴别诊断
Chinese Journal of Ultrasound in Medicine(2014)
Abstract
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.
