Multiple myeloma is a disseminated malignant neoplasm usually derived from a single clone of plasma cells. Patients with myeloma have diverse signs such as anemia, hypercalcemia, uremia, pathologic fractures, and recurrent infections. Extraosseous manifestations are found in less than 5% of patients with multiple myeloma. They can arise in any tissue, and their presence has been associated with more aggressive disease. The purpose of this essay is to illustrate the imaging findings of extraosseous myeloma and heighten awareness of this unusual manifestation of multiple myeloma.
多发性骨髓瘤是一种通常起源于单个浆细胞克隆的播散性恶性肿瘤。骨髓瘤患者有多种体征，如贫血、高钙血症、尿毒症、病理性骨折和反复感染。骨外表现见于不到5%的多发性骨髓瘤患者。它们可出现在任何组织中，其存在与更具侵袭性的疾病相关。本文的目的是阐述骨外骨髓瘤的影像学表现，并提高对多发性骨髓瘤这种不寻常表现的认识。
