A 26-year-old man presented with a retroperitoneal mass with left urinary tract obstruction and hydronephrosis recently. 18F-FDG PET/CT showed the retroperitoneal mass had intense and homogeneous FDG avidity. In 68Ga-FAPI PET/CT, the retroperitoneal mass showed intense radioactivity without other organ involvements. The patient was finally diagnosed with idiopathic retroperitoneal fibrosis. After treatment, the follow-up CT showed significant decrease in size of the retroperitoneal mass. The current case indicated that idiopathic retroperitoneal fibrosis had active uptake of 68Ga-FAPI.
一位 26 岁男性因腹膜后肿块伴左侧尿路梗阻和肾积水就诊。18F-FDG PET/CT 显示腹膜后肿块 FDG 摄取强烈且均匀。68Ga-FAPI PET/CT 显示腹膜后肿块放射性摄取强烈，无其他器官累及。患者最终诊断为特发性腹膜后纤维化。治疗后，随访 CT 显示腹膜后肿块明显缩小。本病例表明特发性腹膜后纤维化对 68Ga-FAPI 有活跃摄取。
