In patients presenting with multiple space-occupying lesions, preserved general condition, and normal or mildly elevated tumor markers, IgG4-related disease (IgG4-RD) should be considered in the differential diagnosis. We report an extremely unusual case of IgG4-RD mimicking metastatic malignancy, with polyserositis and widespread abdominal lymphadenopathy.
对于出现多个占位性病变、一般状况良好且肿瘤标志物正常或轻度升高的患者，鉴别诊断时应考虑IgG4相关性疾病（IgG4-RD）。我们报告了一例极为罕见的IgG4-RD病例，其表现类似转移性恶性肿瘤，伴有多浆膜炎和广泛的腹部淋巴结病。
