目的:提高对肾嗜酸性细胞瘤的诊疗水平。方法:回顾性分析3例经手术、病理证实为肾嗜酸性细胞瘤患者的临床资料。结果:B超检查均提示肾脏占位性低回声病变。CT检查提示肿瘤直径30～55 mm,高密度影2例,等密度肿瘤影1例,增强后2例有不同程度的强化。术后随访1～36个月未见肿瘤转移及复发。结论:肾嗜酸性细胞瘤在临床表现和影像学检查上在术前难以与肾癌鉴别,术中冰冻病理可明确诊断。肾嗜酸性细胞瘤可采取肾部分切除术,预后良好。
Objective: To improve the diagnosis and treatment of renal eosinophoblastoma. Methods: The clinical data of 3 patients with renal eosinophocytoma confirmed by operation and pathology were retrospectively analyzed. Results: B-ultrasound showed renal hypoechoic lesions. CT examination showed that the tumor size was 30-55 mm in diameter, 2 cases with high density and 1 case with isograd tumor. After enhancement, 2 cases had enhancement to some extent. Follow-up 1 to 36 months after surgery, no tumor metastasis and recurrence. Conclusion: Renal eosinophocytoma is difficult to differentiate from renal cell carcinoma in preoperative and radiological manifestations. Intraoperative frozen pathology can be clearly diagnosed. Renal eosinophilia can take partial nephrectomy, the prognosis is good.
