A 52-year-old man was admitted to our hospital with lower abdominal and low back pain, and abdomen CT at an outside hospital presented a retroperitoneal mass with left urinary tract obstruction and hydronephrosis. In 68 Ga-pentixafor PET/CT, the retroperitoneal mass showed intense radioactivity. Subsequently, the patient underwent biopsy of the retroperitoneal mass. The pathological examination showed only fibrous tissue without tumor cells. The patient was finally diagnosed with idiopathic retroperitoneal fibrosis. Our case demonstrated that idiopathic retroperitoneal fibrosis had intense uptake of 68 Ga-pentixafor.
一位 52 岁男性因下腹部和下背部疼痛就诊于我院，外院腹部 CT 提示腹膜后肿块伴左侧尿路梗阻和肾积水。68Ga-戊替曲塞 PET/CT 显示腹膜后肿块放射性摄取明显增高。随后患者行腹膜后肿块活检。病理检查仅见纤维组织，未见肿瘤细胞。患者最终被诊断为特发性腹膜后纤维化。本病例表明特发性腹膜后纤维化对 68Ga-戊替曲塞摄取明显增高。
