A 56-year-old women was admitted for examination of glycosuria. She had had a blunt trauma onto the left abdomen 2 years ago that could have caused renal injury. Incidentally a left renal mass was detected by ultrasonography as a low echogenic mass. CT scan revealed a 2.5 X 2.5 cm mass with lower density than the kidney. IVP and renal angiography showed no abnormal findings. Under the diagnosis of renal tumor, left nephrectomy was performed. A 2 X 2 cm butter-yellow tumor, was seen in the renal parenchyma including the renal capsule of the upper and lateral part of the kidney. The renal pelvis was normal and there were no suppurative lesions in the kidney. Histopathological diagnosis was xanthogranuloma of the kidney partly containing a subcapsular hematoma. The previous blunt trauma, presence of hematoma and no evidence of suppurative lesions suggested that the etiology of xanthogranuloma in this case was related to renal injury.
一名56岁女性因糖尿检查入院。她两年前左腹部曾遭受钝性创伤，可能导致了肾损伤。偶然间，超声检查发现左肾有一个低回声肿块。CT扫描显示一个2.5×2.5厘米的肿块，密度低于肾脏。静脉肾盂造影和肾血管造影未发现异常。在诊断为肾肿瘤后，进行了左肾切除术。在肾脏实质包括肾上极和外侧肾包膜处可见一个2×2厘米的黄油样黄色肿瘤。肾盂正常，肾脏无化脓性病变。组织病理学诊断为肾黄色肉芽肿，部分含有包膜下血肿。既往的钝性创伤、血肿的存在以及无化脓性病变的证据表明，该病例中黄色肉芽肿的病因与肾损伤有关。
