本文对68例行CT扫描经手术病理和临床证实的肾肿瘤进行回顾性分析,恶性肿瘤占93％,良性肿瘤占7％。肿瘤外突致肾外形增大,肿瘤呈低密度、多数有液化坏死以及肾盂、肾盏破坏是肾恶性肿瘤的主要CT所见。11例肿瘤内见钙化者均为恶性,而肿瘤内脂肪和软组织成分混杂是肾血管平滑肌脂肪瘤的特征性表现,也是诊断的关键,所有成人恶性肿瘤中无一例查及脂肪成分。笔者认为常见肿瘤的少见类型和表现以及罕少见肿瘤是误诊的主要原因。本文CT肾肿瘤检出率为100%,诊断准确率为91％。CT对肾肿瘤诊断和鉴别诊断有极高的价值。
In this paper, we retrospectively reviewed 68 cases of pathologically confirmed and clinically confirmed renal tumors, accounting for 93% of malignant tumors and 7% of benign tumors. Tumor outside the sudden increase in renal appearance, the tumor was low density, the majority of liquefied necrosis and renal pelvis, calyx destruction is the main CT findings of renal cancer. Eleven cases of intracranial calcification were malignant, and intramuscular fat and soft tissue components are characteristic of renal angiomyolipoma, which is also the key to diagnosis. None of the adult malignant tumors examined fat composition. The author believes that the rare type and manifestation of common tumors and rarely rare tumors are the main cause of misdiagnosis. CT renal tumor detection rate of 100%, the diagnostic accuracy rate of 91%. CT diagnosis and differential diagnosis of renal tumors have a high value.
