浸润性肾移行细胞癌(TCC)少见。实质受广泛浸润时,TCC很难与肾细胞癌(RCC)、淋巴瘤或转移性疾病鉴别。作者报导经证实(6例经细针抽吸活检和3例手术)为TCC的9例CT和7例US所见。CT检查均注射造影剂后扫描;取层厚5mm,间隔5mm。结果见到,肿瘤大小为5～12cm,平均8.5cm。弥散性浸润肿块6例,稀疏肿块3例。肿瘤累及整个肾6例;3例肿瘤占肾的30～50%。7例肿块位于中心;2例位于肾外周。2例肾盂积水。尿路造影显示病变侧输尿管完全梗阻
Invasive renal cell carcinoma (TCC) rare. TCC is difficult to differentiate from renal cell carcinoma (RCC), lymphoma or metastatic disease when substantially infiltrated. The authors reported 9 cases of CT and 7 cases of proven TCC confirmed by fine needle aspiration biopsy and 3 surgeries. CT examination were injected contrast agent after scanning; take layer thickness 5mm, interval 5mm. The results see, the tumor size of 5 ~ 12cm, an average of 8.5cm. Diffuse infiltration of 6 cases of mass, sparse mass in 3 cases. Tumors involving the entire kidney in 6 cases; 3 cases of tumors accounted for 30 to 50% of the kidney. Seven cases were located in the center of the mass; two were located in the periphery of the kidney. 2 cases of hydronephrosis. Urography showed complete obstruction of the ureter on the side of the lesion
