The clinical and radiographic features of Wilms' tumor in 4 adult patients are described. Wilms' tumors in adults are usually bulky and contain numerous areas of necrosis and hemorrhage, imparting a complex appearance to the lesion on sonography and computed tomography. Angiography reveals the tumor to be hypovascular with some neovascularity. No specific features of the lesion differentiate it from hypernephroma. In contrast to the childhood variety, Wilms' tumors in adults have ill-defined margins and frequently extend into the retroperitoneum. Their treatment is the subject of debate and prognosis is poor.
描述了4例成年患者肾母细胞瘤的临床和影像学特征。成人肾母细胞瘤通常体积较大，包含多个坏死和出血区域，在超声和计算机断层扫描上使病变呈现出复杂的外观。血管造影显示肿瘤血管较少，有一些新生血管。该病变没有与肾细胞癌相鉴别的特异性特征。与儿童型肾母细胞瘤不同，成人肾母细胞瘤边界不清，常延伸至腹膜后。其治疗存在争议，预后较差。
