An analysis of the CT findings in 14 cases of pathologically verified renal cell carcinoma and 1 case of renal pelvis carcinoma was presented. Examination included plain and contrast enhanced CT scan. The CT appearances of renal cell carcinoma are: (1) Hypodense masses on plain scan; (2) Hypodense masses more clear compared with parenchyma after contrast enhancement; (3) An uns arp interface with the surrounding parenchyma; (4) Metastatic signs revealed enlargement of renal vein, involvement of regional lymph...

An analysis of the CT findings in 14 cases of pathologically verified renal cell carcinoma and 1 case of renal pelvis carcinoma was presented. Examination included plain and contrast enhanced CT scan. The CT appearances of renal cell carcinoma are: (1) Hypodense masses on plain scan; (2) Hypodense masses more clear compared with parenchyma after contrast enhancement; (3) An uns arp interface with the surrounding parenchyma; (4) Metastatic signs revealed enlargement of renal vein, involvement of regional lymph nodes, invasion of the inferior vena cava and distant metastasis. The CT findings of renal pelvis carcinoma are quite characteristic. Precontrast scan revealed soft tissue mass in the dilated pelvis. After contrast enhancement the density of the mass increased as crescentie thickening of the wall and extending into the pelvis. Significance of various CT appearances of renal carcinoma and differential diagnosis from other renal masses were discussed.

本文分析了病理证实的14例肾细胞癌和1例肾盂癌的CT表现。检查方法包括增强前、后CT扫描。肾细胞癌常见的CT表现为:(1)增强前为低密度肾实性肿块;(2)增强后低密度肿块显示更清楚;(3)肿块与周围。肾实质分界不清;(4)转移性改变为肾静脉增粗、局部淋巴结肿大、下腔静脉受累以及远处转移。肾盂癌的CT表现颇具特征。增强前扫描扩张的肾盂内可见到软组织肿块。增强后肾盂壁呈新月形增厚并突向扩大的肾盂形成密度增高的软组织块影。文中讨论了肾癌各种CT表现的意义及其与其他肾占位病变的鉴别诊断。

The preoperative CT data of renal tumors in 53 cases were analysed, and compared with operation and pathologic examination or follow-up survey.An accurate preoperative CT diagnosis was achieved about 94.3%.The overal staging accuracy of renal cell carcinoma was 85.3%.CT is superior to either ultrasound or IVP in the diagnosis of renal tumors.The density of renal cell carcinoma on precontrast CT scans is related to its pathologic type.In clear cell carcinoma the density is usually lower than that of the normal...

The preoperative CT data of renal tumors in 53 cases were analysed, and compared with operation and pathologic examination or follow-up survey.An accurate preoperative CT diagnosis was achieved about 94.3%.The overal staging accuracy of renal cell carcinoma was 85.3%.CT is superior to either ultrasound or IVP in the diagnosis of renal tumors.The density of renal cell carcinoma on precontrast CT scans is related to its pathologic type.In clear cell carcinoma the density is usually lower than that of the normal renal parenchyma or approximate to the normal renal parenchyma, and in granular cell type, the density is higher than that of the normal renal parenchyma.Nonperipheral mottled calcification of the renal mass is the character of malignancy in CT.

本文分析我院术前CT拟诊肾肿瘤,并有手术、病理或随访结果进行对照的53例CT资料,探讨CT对肾肿瘤的诊断反对肾细胞癌术前分期的价值,53例中CT诊断正确50例(94.3%),肾细胞癌术前分期整体正确率85.3%。对肾肿瘤的诊断,CT优于B超和静脉肾孟造影,平扫时肾癌密度与病理类型有关,透明细胞癌多为低密度或近似等密度,颗粒细胞癌多为高密度。肾肿块内部斑点状钙化是恶性肿瘤的CT特征。

The preoperative CT data of 43 cases of kidney neoplasm were reviewed with comparative studies of operative and pathologic findings. 38 were renal cell carcinoma, 2 renal benign tumor, 3 inflammatory pseudotumor. The dicussion centred on the CT diagnosis of Various renal masses, especially early diagnosis, and differential diagnosis as well as CT stages. About 50% of renal masses were detected in early physical examination (B—type ultrasound or CT scan). It is very important for differential diagnosis that the...

The preoperative CT data of 43 cases of kidney neoplasm were reviewed with comparative studies of operative and pathologic findings. 38 were renal cell carcinoma, 2 renal benign tumor, 3 inflammatory pseudotumor. The dicussion centred on the CT diagnosis of Various renal masses, especially early diagnosis, and differential diagnosis as well as CT stages. About 50% of renal masses were detected in early physical examination (B—type ultrasound or CT scan). It is very important for differential diagnosis that the CT features such as density, shape, calcification and so on were analysed carefully. Do not ignore the CT stages in the treatment of renal cell carcinoma.

本文回顾性分析了有手术病理及细胞学诊断对照的43例肾占位性病变的CT表现,其中肾细胞癌38例,良性肾肿痛2例,炎性假瘤3例。重点讨论了CT对于肾肿瘤的诊断尤其是早期诊断和鉴别诊断,以及CT分期。认为50%的肾肿瘤可以在早期健康查体中发现。肾肿瘤的密度,形态,钙化等CT征象的分析是鉴别诊断的关键,而CT分期更是临床治疗所不容忽视的。
