目的研究肾癌侵犯肾周间隙的CT征象和病理特点。方法回顾分析我院经手术及病理证实肾癌累及肾周间隙的病例40例。结果肾周间隙受侵的CT征象可有多发结节、条索状影、棘状突起和肾周筋膜增厚,与肾癌肿块最大径及进展期肾癌分期有相关性,其病理改变包括肾周间隙内淋巴结转移、肿瘤直接侵犯或压迫引起的血管曲张、肾周间隙内的桥间隔的液体聚积等。结论正确分析掌握肾癌对肾周间隙侵犯的CT征象有助于提高肾癌术前分期诊断的准确性。
Objective To study the CT features and pathological features of renal peritoneal space infiltrating renal cell carcinoma. Methods Retrospective analysis of 40 cases of renal cell carcinoma involving renal peritoneal space confirmed by surgery and pathology in our hospital. Results CT signs of peritoneal space invasion may have multiple nodules, cords, spinous processes and perirenal fascia thickening, with the maximum diameter of renal cell carcinoma and advanced stage of renal cell carcinoma, the pathological changes Including perirenal lymph node metastasis, tumor invasion or compression caused by vascular varicose, interstitial renal interstitial fluid accumulation within the bridge interval. Conclusion Correct analysis of the CT features of renal cell carcinoma on the perirenal space can help to improve the accuracy of the preoperative staging of renal cell carcinoma.
