CT findings of 10 cases of transitional cell carcinoma with renal parenchymal involvement were reviewed. CT showed a low-density mass with varying degrees of renal parenchymal involvement. Intrarenal transitional cell carcinomas were characterized by preserved renal contour with abnormalities of the collecting system such as obliteration, entrapment in the tumor, dilatation, and intraluminal mass. Obliteration of the renal sinus fat and poorly defined tumor margin were other characteristic CT features. This study indicated that CT is useful for differentiating transitional cell carcinomas with renal parenchymal involvement from renal cell carcinomas.
回顾了10例伴有肾实质受累的移行细胞癌的CT表现。CT显示为低密度肿块，伴有不同程度的肾实质受累。肾内移行细胞癌的特征是肾轮廓保留，集合系统存在异常，如闭塞、被肿瘤包绕、扩张和腔内肿块。肾窦脂肪消失和肿瘤边缘不清是其他特征性CT表现。本研究表明，CT有助于鉴别伴有肾实质受累的移行细胞癌与肾细胞癌。
