摘要
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 characteristics of perinephric space abnormalities in renal cell carcinoma. Methods Perinephric space abnormalities in renal cell carcinoma proved by pathology after their surgery in 40 patients were reviewed. Results CT features of perinephric space abnormalities in these 40 cases included nodus, trabs, spine-like process and thickening of the perirenal fascia, which were correlated to the largest tumor diameter of renal cell carcinoma and advanced stages of renal cell carcinoma. The pathological foundation included lymph node metastasis of perinephric space, the varix of perinephric space caused by direct encroachment or oppression of tumor, the effusion of the bridge septa in the perinephric space, etc. Conclusion It is useful for elevating the accuracy rate of CT staging of renal cell carcinoma that we correctly master the CT features of perinephric space abnormalities in renal cell carcinoma.
