Simultaneous bilateral presentation of psoas abscess with prosthetic joint involvement is extremely rare. A 68-year-old woman presented to us with bilateral dull aching groin pain of 6 months' duration, which flared up in the past month, associated with pyrexial symptoms. She had undergone bilateral hip replacements in the past with uneventful recovery. MRI showed bilateral psoas muscle collection in communication with the hip joints. Preoperative hip aspirate demonstrated frank pus with positivity on Gram stain and radiographs confirmed prosthetic loosening of bilateral hips. The patient subsequently underwent two-stage revision arthroplasty of both infected hip implants. At 5-year follow-up, the patient remains asymptomatic with good functional outcome and no recurrence on serial MRI.
同时双侧出现伴有人工关节受累的腰大肌脓肿极为罕见。一名68岁女性因持续6个月的双侧腹股沟隐痛前来就诊，该疼痛在过去一个月加重，并伴有发热症状。她过去曾接受双侧髋关节置换术，恢复顺利。磁共振成像显示双侧腰大肌有积液并与髋关节相通。术前髋关节穿刺抽出脓性液体，革兰氏染色呈阳性，X线片证实双侧髋关节假体松动。患者随后接受了双侧感染髋关节假体的两期翻修置换术。在5年的随访中，患者无症状，功能恢复良好，连续磁共振成像检查未发现复发。
