【摘要】 目的 探讨肝、肾血管平滑肌脂肪瘤即错构瘤的临床特点、影像诊断以及鉴别诊断。方法 回顾性分析1例51岁女性患者肝、肾错构瘤的临床资料,结合文献报道,对其临床表现、影像特点进行探讨。结果 腹部CT示扫示肝右叶一巨大低密度占位,增强扫描动静脉期自周缘向中心渐进性填充。两肾体积明显增大,呈大小不等、形态各异的蜂巢状混杂密度,可见斑块状、条索状的脂肪密度,增强扫描正常皮髓结构消失,蜂巢壁明显强化,其内见未强化区,双肾动静脉明显受压、移位。结论 肝、肾错构瘤与肝、肾其它良性、恶性病变相比,影像表现较典型,但确诊多数只能通过病理组织学方法。更多还原

【Abstract】 Objective To investigate the imaging manifestations and clinical features of hepatic and renal angiomyolipoma.Methods The clinical data and imaging findings of hepatic and renal angiomyolipoma in a 5-year-old woman was retrospectively analyzed with literature review.Results CT scan showed a large polymorphous hypodense mass in the right lobe of liver.After contrast-enhanced CT scan,the mass was enhanced gradually from periphery to centre.Bilateral kidneys obviously enlarged and appeared as alveolate appearance mixed density with spotty and stripped fat structures.At contrast-enhanced scan,the normal structures of cortex and medulla were disappeared,the alveolate walls were enhanced obviously.The arteries and veins of bilateral kidneys were compressed and displaced.Conclusion The imaging features of liver and kidney are of certain characteristic compared with other benign and malignant masses,but the final diagnosis of it is still depending on pathology mostly.更多还原
