1、肾脏嗜酸细胞腺瘤的螺旋CT诊断与病理对照分析【摘要】目的：分析肾嗜酸细胞瘤的多排螺旋CT增强扫描特征及病理表现，以提高诊断准确性。方法：对12例经手术后病理证实的肾嗜酸细胞腺瘤患者的多期增强CT影像学特点及病理结果进行回顾性分析。结果：11例为单发病灶，1例为多发病灶。病灶最大径20.0〜87.0mm,平均53.5mmo1例行CT平扫显示肿瘤实质呈略高密度影，中心瘢痕呈低密度影。皮质期5例不均匀强化，6例肿瘤实性部分较均匀强化，所有病灶强化程度均高于髓质，低于皮质；实质期病灶强化程度均低于髓质，2例欠均匀强化，10例病灶密度趋向均匀强化；延迟期肿瘤实性部分整体密度较均匀强化并低于
2、肾实质，与病理上该肿瘤较少发生出血、坏死、囊变相对应。其中1例双肾多灶病变亦遵循上述强化方式。6例见中央裂隙状或星芒状瘢痕，所有病例均未见钙化。结论：肾嗜酸细胞瘤是一种少见的肾脏良性肿瘤，多期螺旋CT增强扫描有一定影像学特点，如果能在术前提示到本病的可能性，可采取肾穿刺活检或手术中冰冻病理活检，对临床手术治疗方案的制定有重要参考意义。【关键词】肾嗜酸细胞腺瘤；诊断；螺旋CT；病理TheComprehensiveDiagnosisofRenalOncocytomabySpiralCTandPatho1ogy/ZHANGQing,LIJun~tang,ZHANGJin-feng,et
