目的探讨浸润型肾盂癌的CT影像特征,旨在提高对其诊断与鉴别诊断的能力。方法回顾性分析经手术病理证实的13例浸润型肾盂癌CT表现特征。结果 13例浸润型肾盂癌均位于肾轮廓之内,肾体积局部略增大,但轮廓无明显改变。12例平扫密度呈等或略低密度且均匀,均未见钙化。13例增强扫描呈轻-中度强化。9例行肾动脉CTA检查显示动脉无受侵,分支无增粗。2例伴有输尿管和膀胱发病。结论 CT对浸润型肾盂癌的诊断和鉴别诊断具有一定的临床实用价值。
Objective To investigate the features of CT images of infiltrating renal pelvis cancer and to improve its ability of diagnosis and differential diagnosis. Methods Retrospective analysis of 13 cases of invasive renal pelvic carcinoma confirmed by surgery and pathology CT features. Results Thirteen cases of infiltrating renal pelvic carcinoma were located in the renal outline, the renal volume of the local slightly increased, but no significant change in contour. 12 cases of plain density was equal or slightly lower density and uniform, no calcification. Thirteen enhanced scans showed mild to moderate enhancement. 9 cases of renal artery CTA showed no invasion of arteries, branches without thickening. 2 cases with ureteral and bladder disease. Conclusion CT has certain clinical value in the diagnosis and differential diagnosis of invasive renal pelvic cancer.
