Citrobacter koseri causes opportunistic infections in various organs. We herein report an 84-year-old man with diabetes mellitus who presented to our hospital with left hip pain and walking difficulty. Computed tomography showed an extensive abscess with gas production, mainly in the left retroperitoneal space, caused by C. koseri infection. Despite daily cleaning of the wound and antimicrobial therapy (with surgical drainage), the patient developed repeated pneumonia and small bowel hemorrhaging caused by disseminated intravascular coagulation and died on day 65 of hospitalization. Overall, retroperitoneal abscesses caused by C. koseri are rare, and multiple abscesses may show a poor prognosis.
柠檬酸杆菌引起多种器官的机会性感染。我们在此报告一位 84 岁男性糖尿病患者，因左髋部疼痛和行走困难就诊我院。计算机断层扫描显示广泛脓肿伴产气，主要位于左腹膜后间隙，由柠檬酸杆菌感染引起。尽管每日清创和抗菌治疗（手术引流），患者因弥漫性血管内凝血出现反复肺炎和小肠出血，住院第 65 天死亡。总体而言，柠檬酸杆菌引起的腹膜后脓肿罕见，多发脓肿可能预后不良。
