作者在10年间发现45例(8男,6女,年龄30~72岁)肾肉瘤和肉瘤样肾细胞癌,并回顾性地研究了CT和血管造影的表现。14例患者均经腹部CT检查,11例行血管造影(包括选择性双肾、肝血管及下腔静脉造影)。肿瘤位于右肾者8例,左肾6例。其中肉瘤样肾细胞癌4例,平滑肌肉瘤3例,脂肪肉瘤2例,纤维肉瘤2例,恶性纤维性组织细胞瘤,透明细胞肉瘤和未分类的肾脏肉瘤各1例。14例中,CT发现8例肿瘤起自肾实质,4例起自肾被膜,1例起自肾窦,1例肿瘤起源不明。11例血管造影中4例肉瘤样肾细胞癌与2例平滑肌肉瘤为多血管性者,其余5例肿瘤为少血管或无血管性
Forty-five (8 males, 6 females, aged 30-72 years) with sarcomatoid and sarcomatoid renal cell carcinoma were identified over 10 years and the CT and angiographic findings were retrospectively reviewed. All 14 patients underwent abdominal CT examination and 11 underwent angiography (including selective bilateral renal, hepatic vessels and inferior vena cava angiography). Tumor located in the right kidney in 8 cases, 6 cases of left kidney. Including sarcomatoid renal cell carcinoma in 4 cases, 3 cases of leiomyosarcoma, liposarcoma in 2 cases, 2 cases of fibrosarcoma, malignant fibrous histiocytoma, clear cell sarcoma and unclassified renal sarcoma in 1 case. Among the 14 cases, eight cases of tumors from the kidney were found from the renal parenchyma, four from the renal capsule, one from the renal sinus and one from the tumor. Of the 11 cases of angiography, 4 cases of sarcomatoid renal cell carcinoma and 2 cases of leiomyosarcoma were multi-vascular, and the remaining 5 cases were of little or no vascular
