Abstract:
Objective To analyze the CT imaging features of renal parenchymal urothelial carcinoma and other renal infiltrative lesions,and to improve the diagnostic and differential diagnostic accuracy of renal parenchymal urothelial carcinoma.Methods The clinical and imaging data from 60 patients with renal infiltrative lesions involving both the renal pelvis and renal parenchyma confirmed by pathology were collected,including 27 cases of renal parenchymal urothelial carcinoma,20 cases of renal papillary cell carcinoma,and 13 cases of renal lymphoma.All patients underwent plain and three-phase enhanced scans.Clinical manifestations and imaging fea-tures were analyzed,and the tumor/cortex CT ratio was measured on plain and three-phase enhanced scans,and statistically ana-lyzed.Results The renal contour of some patients with renal papillary cell carcinoma was altered and locally protruded beyond the contour,while the remaining patients had a normal renal morphology,with involvement of either a renal segment or the entire kid-ney,and unclear cortex-medulla differentiation.All three types of tumors showed mild to moderate progressive enhancement.The tumor/cortex CT ratio on plain scan had no statistical significance among the three groups(P＞0.05),while the tumor/cortex CT ratio on three-phase enhanced scan showed statistical significance(P＜0.05).Conclusion There are differences in imaging manifes-tations between renal parenchymal urothelial carcinoma and other renal infiltrative lesions,with significant differences in the phase of peak enhancement.
