| 中文摘要: |
| 目的：探讨螺旋CT 和MRI 对肾嗜酸性细胞腺瘤的诊断及鉴别诊断的价值。方法：回顾性分析12 例肾嗜酸性细胞瘤的CT
和/ 或MRI 表现。结果：CT 检查12 例，平扫8 例病灶呈均匀软组织密度影，3 例呈不均匀软组织密度影，1 例瘤体周边有环状钙
化。增强后病灶轻中度强化，6 例见星状瘢痕。MRI 检查3 例，2 例T1WI 呈等低信号、T2WI 呈高信号；1 例T1WI 呈等信号、T2WI
等低信号。结论：多数肾嗜酸细胞腺瘤的影像学表现具有一定特征性。CT 结合MRI 特别是动态扫描有助于术前做出正确的诊断。 |

| Objective: To investigate the value of spiral CT and MR in the diagnosis and differentiatial diagnosis of renal
oncocytoma. Methods：The data of CT and/or MRI of 12 patients with renal oncocytoma were reviewed retrospectively. Results：Twelve
cases were performed CT scans. Eight cases showed homogeneous, three cases showed heterogeneous in pre-contrast CT scans, and one
case showed annular calcification around the lesion. All of them were visualized as mild or medium enhancement, and six of them were
found with central scar. Three cases were performed MRI scans. Two cases were heterogeneous iso-hypointense on T1WI, and
hyperintense signal on T2WI. One case was isointense signal on T1WI and iso-hypointense signal on T2WI. Conclusion：Most of the
oncocytomas showed certain characteristics, the combined examinations of CT and MRI, especially triphasic CT imaging , can provide
more useful information for preoperative diagnosis. |
