Extramedullary disease in multiple myeloma is uncommon and associated with a poorer prognosis. Extramedullary disease involving the orbit is even more unusual, with optic nerve involvement being rare. We describe an optic nerve head plasmacytoma in a 45-year-old female in the setting of systemic relapsed, refractory IgA kappa multiple myeloma. The case highlights the importance of keeping extramedullary disease spread in the differential for vision loss in a patient with a history of multiple myeloma. In addition, it describes an unusual location for presentation of extramedullary disease, the optic nerve head, which has rarely been described.
多发性骨髓瘤的髓外病变并不常见，且预后较差。累及眼眶的髓外病变更为罕见，视神经受累则极为罕见。我们报告一例45岁女性患者，在系统性复发、难治性IgA κ型多发性骨髓瘤背景下出现视神经乳头浆细胞瘤。该病例凸显了在有骨髓瘤病史的患者中，将髓外病变扩散纳入视力丧失鉴别诊断的重要性。此外，它描述了髓外病变的一个不寻常的发病部位——视神经乳头，此前鲜有报道。
