Abstract

Background

Perirenal hematomas are commonly observed in patients with renal trauma; however, secondary infections are uncommon and often underdiagnosed.

Case Presentation

An 82-year-old woman with a history of diabetes mellitus and liver cirrhosis presented to our emergency department with intermittent fever, malaise, and lower back pain 1 month after sustaining a fall. Contrast-enhanced computed tomography (CT) showed an 8-cm gas-containing left perirenal hematoma without urinary extravasation, and blood culture revealed Klebsiella pneumoniae. The patient was initially treated with intravenous antibiotics; however, CT-guided percutaneous drainage was eventually required for clinical and radiologic resolution.

Conclusion

Delayed-onset infection in traumatic perirenal hematoma needs to be considered in high-risk patients for early definitive source control.

创伤后迟发性感染肾周血肿1例报告

背景：肾周血肿常见于肾外伤患者；然而，继发性感染并不常见，而且往往未被确诊。病例介绍：一名82岁女性，有糖尿病和肝硬化病史，在持续跌倒1个月后以间歇性发热、不适和腰痛就诊于急诊科。CT增强扫描示左侧肾周血肿8厘米含气，无尿外渗，血培养示肺炎克雷伯菌。患者最初接受静脉注射抗生素治疗；然而，最终需要ct引导下的经皮引流来解决临床和放射学问题。结论：外伤性肾周血肿的迟发性感染需要在高危患者中进行早期明确的传染源控制。
