Progressive multifocal leukoencephalopathy (PML) can rarely occur in individuals with occult immunosuppression. Here, we describe the case of an adult man who presented with PML, in whom CD4+ lymphocytopenia and hypogammaglobulinemia were subsequently identified, leading to a diagnosis of late-onset combined immunodeficiency. Intravenous immunoglobulin replacement therapy was initiated. His clinical course, though complicated by immune reconstitution inflammatory syndrome, was favorable.
进行性多灶性白质脑病(PML)很少发生于隐匿性免疫抑制个体。在此,我们描述一例成年男性患者,该患者表现为PML,随后发现其存在CD4 +淋巴细胞减少和低丙种球蛋白血症,最终诊断为迟发性联合免疫缺陷。遂开始静脉注射免疫球蛋白替代治疗。尽管该患者的临床病程因免疫重建炎症综合征而复杂化,但总体预后良好。
