摘要
目的:分析病理性肾损伤的影像学表现特征,评价CT和MRI对病理性肾损伤及其病因的诊断价值。方法:回顾性分析9例病理性肾损伤的临床资料及影像学表现,9例均有不同程度的外伤史,全部经CT检查(7/9增强),5例经MRI检查(4/5增强)。结果:病理性肾损伤的病因中,血管平滑肌脂肪瘤3例,肾癌2例,黄色肉芽肿性肾盂肾炎、多发肾囊肿、神经源性膀胱炎伴肾积水、先天性肾盂输尿管连接部狭窄伴肾积水各1例。8例经手术病理证实,1例经临床既往病史证实。CT和MRI检查均清楚显示原发病变及损伤表现。结论:CT和MRI检查对病理性肾损伤的价值显著,但对病因的定性诊断有局限性。
Objective：To analyze imaging features of pathologic renal trauma and to evaluate the value of Computed Tomography and MR imaging in the diagnosis of pathologic renal trauma. Methods：Tile clinical materials and imaging appearances of 9 cases with pathologic renal tratuna were retrospectively analyzed. All of them had histories of trauma. CT examinations were perfomled in all 9 cases （7 cases had contrast-enhanced scans） and, MRI in 5 eases （4 cases had contrast-enhanced scans）. Results： The causes of pathologic renal trauma in this group included angiomyolipama in 3 cases, renal carcinoma in 2 cases, xanthogranulomatous pyeloneptn＇ifis in one case, multiple renal cysts in one case, neurogenie bladder complicated hydronephrosis in one ease, and congenital ureteropelvic junction obstruction complicated hydronephrosis in one case. 8 cases were confirmed by pathology and one case was confirmed by previous clinic history. Primary diseases and traumatic lesions were all clearly manifested by CT and MRI. Conclusion： Mthough the limitation in the etiologic diagnosis of primary diseases, CT and MRI are very useful techniques for the diagnosis of pathologic renal trauma.
