Abstract：
This is a case of a 42-year-old man with recurrent symptoms of dizziness and a newly found retroperitoneal mass with no 131I-MIBG uptake who was referred for restaging with 68Ga-DOTATATE PET/CT and local 68Ga-pentixafor PET/CT. The examinations both showed intense radioactivity uptake in the retroperitoneal mass and no abnormal uptake in the right adrenal nodule. Two lesions showed distinct properties of radioactivity uptake, which suggested the possibility of different sources. A postoperative pathological test revealed that the morphology and immunohistochemistry of the retroperitoneal mass was found to be consistent with Castleman disease, and the right adrenal gland was normal tissue.
摘要：
这是一例42岁男子，反复出现头晕症状，新发现腹膜后肿块，无131I-MIBG摄取，被转诊为68Ga-DOTATATEPET/CT和局部68Ga-pentixaforPET/CT。检查均显示腹膜后肿块有强烈的放射性摄取，右肾上腺结节无异常摄取。两个病变显示出不同的放射性摄取特性，这表明了不同来源的可能性。术后病理检查发现腹膜后包块的形态和免疫组化与Castleman病一致,右肾上腺为正常组织。
