目的探讨肾透明细胞癌的磁共振成像(MRI)与病理表现的关系.方法对23例经术后病理证实的肾透明细胞癌患者术前MRI征象及术后病理结果进行回顾性对照分析.结果 MRI平扫:2例信号均匀,21例信号混杂,见囊变、坏死,11例见出血,12例见假包膜.动态增强扫描:实性部分明显强化,皮质期强化程度低于肾皮质,高于肾髓质,髓质期、延迟期持续强化.术后肿瘤剖面呈黄白色,病灶内见囊性及坏死结构,17例可见出血.光学显微镜下观察,肿瘤细胞常呈实体巢状或腺泡状排列,间质内富含薄壁血管构成网状间隔,14例可见假包膜.结论肾透明细胞癌的MRI表现与组织结构有关,MRI平扫结合动态增强扫描对肾透明细胞癌的诊断有较高价值.

Objective To study the relationship between MRI features and pathological characteristics of the renal clear cell carcinoma,and to conduct a comparative analysis.Methods 23 patients renal clear cell carcinoma who were proved by postoperative pathology were retrospectively analyzed. The preoperative MRI findings and the postoperative pathological characteristics were compared. Results MRI plain scan showed uniform signal was seen in 2 cases, and mixed signal was found in 21 cases with cystic and necrosis. Blood was seen in 11 cases and false envelope was present in 12 cases. Dynamic enhanced scanning revealed that solid part was enhanced obviously, it was lower than the renal cortex but higher than the renal medulla in cortical phase and continued to be enhanced in medullary phase and delay phase.Postoperative pathological characteristics showed that tumor profiles were yellow-white and cystic and necrotic structures were present within tumors, blood was found in 17 cases. Endoscopic tumor cells were present in solid nests or acinar structure, and mesenchyma was rich in thin-walled vessels involved in reticular interval.14 cases were found to have false envelope.Conclusion Renal clear carcinoma MRI imaging manifestion is related to organixational srructure. MR plain scan combined with dynamic enhanced scan has very high value in the diangnodis of renal cell carcoinoma.
