A 40-year-old man with history of extramedullary plasmacytoma in nasal cavity presented with right submandibular mass for 3 months. F-FDG PET/CT demonstrated mild radioactivity in the right submandibular mass, pancreatic mass, and lymph nodes in the abdomen and left hilum of the lung. To differentiate from pancreatic neuroendocrine tumor, Ga-DOTATATE PET/CT was performed. The above lesions were TATE avid, and additional lesions with intense radioactivity were also detected in the right internal mammary node and intrapericardial node. Finally, biopsy of the right submandibular mass confirmed recurrence of extramedullary plasmacytoma.
一位 40 岁男性，既往有鼻腔髓外浆细胞瘤病史，现因右侧颌下肿块 3 个月就诊。F-FDG PET/CT 示右侧颌下肿块、胰腺肿块、腹部淋巴结及左肺门淋巴结放射性摄取轻度增高。为鉴别胰腺神经内分泌肿瘤，行 Ga-DOTATATE PET/CT 检查。上述病变摄取 TATE 明显，右侧内乳淋巴结和心包内淋巴结亦见放射性摄取增高病灶。最终，右侧颌下肿块活检证实为髓外浆细胞瘤复发。
