Abstract

Introduction

Hibernomas are benign tumors of brown adipose tissue. Hibernoma in the renal sinus is extremely rare. Herein, we present the third known case of renal hibernoma.

Case presentation

A 71-year-old man reported to our department with a left kidney tumor with an average growth rate of 5 mm/year and a progressive contrast effect on computed tomography. It was diagnosed as a hibernoma following a laparoscopic radical nephrectomy.

Conclusion

We encountered a rare case of a hibernoma in the renal sinus. Development of new and accurate diagnostic methods for hibernoma, without resorting to nephrectomy, is essential.

肾窦内的蛰伏瘤：一个模仿恶性肿瘤的病例

纤维瘤是棕色脂肪组织的良性肿瘤。肾窦内的蛰伏瘤极为罕见。一位 71 岁的男性因左肾肿瘤来我科就诊，肿瘤平均生长速度为 5 毫米/年，且在计算机断层扫描中出现进行性对比效应。我们遇到了一例罕见的肾窦内冬眠瘤病例。我们遇到了一例罕见的肾窦内冬眠瘤病例。在不采用肾切除术的情况下，开发新的、准确的冬眠瘤诊断方法至关重要。
