肾嗜酸粒细胞腺瘤1例报告并文献复习

目的研究肾嗜酸细胞腺瘤（RO）的CT表现。方法1例44岁女性经病理组织学证实为RO患者，继X线胸片，腹部彩色多普勒超声及实验室检查后又经腹部CT平扫与增强扫描。RO的CT表现是结合文献复习分析的。结果CT平扫证实，在右肾下极背侧实质内有一大小约2．4cm×2．2cm的低密度区，边缘清楚，边缘密度高于中央密度。增强扫描皮质期，病灶边缘明显强化，中央呈片状轻度强化，实质期病灶边缘密度减低，中心部位强化伴低密度无强化区，肾盂期病灶边缘密度仍较低，对比剂逐渐向中央填充并呈轻度强化伴缩小的低密度区。结论RO虽然具有某些CT强化特征，但确诊需依据穿刺活检或术后病理。
