Myelolipoma of the kidney is an exceedingly unusual benign tumor of hematological components mixed with mature adipose tissue. We present a case of a 59-year-old male who presented with left flank pain and was found to have an atrophic left kidney on imaging studies. A computed tomography (CT) scan revealed a small and shrunken left kidney with an extrarenal pelvis. A diethylenetriamine pentaacetate (DTPA) scan results showed a total glomerular filtration rate (GFR) of 45.6 ml/min with a non-functional left kidney. The patient underwent a left nephrectomy, and a histopathological examination confirmed the diagnosis and highlighted the distinctive morphological features of this rare entity. Postoperatively, the patient experienced a complete resolution of symptoms. This case underscores the importance of considering myelolipoma in the differential diagnosis of renal masses and highlights the successful management of symptomatic cases through surgical intervention. Awareness of this rare tumor is crucial for accurate diagnosis and appropriate management. Further studies are needed to elucidate the natural history and optimal treatment strategies for renal myelolipomas.
肾髓质脂肪瘤是一种极为罕见的良性肿瘤，由血液学成分与成熟脂肪组织混合而成。我们报告一例59岁男性患者，该患者因左侧胁腹疼痛就诊，影像学检查发现左肾萎缩。计算机断层扫描（CT）显示左肾小且萎缩，伴有肾外肾盂。二乙三胺五乙酸（DTPA）扫描结果显示总肾小球滤过率（GFR）为45.6 ml/分钟，左肾无功能。患者接受了左肾切除术，组织病理学检查确诊并突出了这一罕见实体的独特形态特征。术后，患者症状完全缓解。该病例强调了在肾肿块鉴别诊断中考虑髓质脂肪瘤的重要性，并突出了通过手术干预成功治疗有症状病例的情况。认识这种罕见肿瘤对于准确诊断和适当治疗至关重要。需要进一步研究以阐明肾髓质脂肪瘤的自然病程和最佳治疗策略。
