摘要
目的探讨肾盂癌的CT表现及诊断价值。方法回顾性分析23例经手术及病理证实的肾盂癌的CT表现特点。结果乳头状和菜花状移行细胞癌表现为肾盂、肾盏内与肾实质呈等密度结节影。广基浸润移行细胞癌表现为肾盂、肾盏黏膜局限性或较为弥漫性浸润增厚。肾盂癌可侵犯肾实质,很少引起肾轮廓的改变。肾盂癌属少血供肿瘤,动脉期强化不明显,延迟强化。CT诊断与病理诊断一致率为96.13%。结论肾盂癌的CT表现有一定特点,动态增强扫描可反映肿瘤的强化特征,提供有价值的鉴别诊断依据。
Objective To analyze the manifestations of renal pelvic carcinoma on CT and assess its diagnostic value. Methods A retrospective study was carried out on the CT findings of 23 cases of pathologically confirmed renal pelvic carcinoma. Results Papillary and cauliflower-like transitional cell carcinoma（TCC） showed identical density nodules in the renal pelvis,calyces and parenchyma.Sessile infiltrative TCC showed circumscribed or diffused thickening of the renal pelvis and calyces mucosa.Carcinoma of renal pelvis may invade the renal parenchyma.But the renal contour is seldom changed.Carcinoma of renal pelvis is poorly blood-supplied.The tumor is not enhanced in arterial phase,but shows delayed enhancement. Conclusion The characteristic CT findings of renal pelvic carcinoma together with dynamic enhancement provide evidence for differential diagnosis of the tumor.
