■全髋关节置换术(THA)是一种公认的外科手术,已被广泛验证可以减轻疼痛,增强关节功能,提高进行日常活动的能力,提高整体生活质量。然而,这个过程与某些并发症有关,其中骨骼肌纤维化是一种经常被忽视但重要的并发症,可导致持续性疼痛。目前,目前尚无有效的方法诊断全髋关节置换术后骨骼肌纤维化。
■我们报告了一名75岁的男性患者,该患者主诉全髋关节置换术后左腹股沟疼痛。血清学检查,X光片,骨扫描结果均正常。然而,在68Ga-FAPIPET/CT检查期间,我们观察到沿髂腰肌明显的放射性示踪剂摄取。这种异常的摄取模式表明该特定区域具有潜在的生物活性。结合体检,患者被诊断为髂腰肌纤维化。
■显示的图像表明,摄取模式是诊断的重要指标,并展望成纤维细胞活化蛋白在骨骼肌纤维化诊断中显示出一定的应用价值。
UNASSIGNED: Total hip arthroplasty (THA) is a well-established surgical procedure that has been extensively validated to alleviate pain, enhance joint function, improve the ability to perform daily activities, and enhance overall quality of life. However, this procedure is associated with certain complications, among which skeletal muscle fibrosis is a frequently overlooked but significant complication that can lead to persistent pain. Currently, there is no effective method for diagnosing skeletal muscle fibrosis following total hip arthroplasty.
UNASSIGNED: We report a 75-year-old male patient who complained of left groin pain after revision total hip arthroplasty. Serological examinations, X-rays, and bone scan results were all normal. However, during the 68Ga-FAPI PET/CT examination, we observed significant radiotracer uptake along the iliopsoas muscle. This abnormal uptake pattern suggested potential biological activity in this specific area. Combined with physical examination, the patient was diagnosed with iliopsoas fibrosis.
UNASSIGNED: The presented images indicated that the uptake pattern was an important indicator for diagnosis, and the prospect of fibroblast activation protein in the diagnosis of skeletal muscle fibrosis has shown certain application value.
