Extramedullary multiple myeloma (EMM) is a subset of multiple myeloma with a poor prognosis. We report a rare case with biopsy-proven concurrent liver and mesentery primary EMM at the time of initial staging after serologic diagnosis of multiple myeloma. 18F-FDG PET/CT is valuable in detection of EMM when the patient has no osseous lesions and a negative bone marrow biopsy.
髓外多发性骨髓瘤（EMM）是多发性骨髓瘤的一个预后不良的亚型。我们报告了一例罕见病例，在血清学诊断多发性骨髓瘤后的初始分期时，经活检证实同时存在肝和肠系膜原发性 EMM。当患者没有骨病变且骨髓活检阴性时，18F-FDG PET/CT 对 EMM 的检测具有重要价值。
