目的探讨胸椎弥漫大B细胞淋巴瘤与脊柱关节炎的鉴别诊断。方法分析1例老年胸椎弥漫大B细胞淋巴瘤患者误诊为脊柱关节炎的临床资料。结果患者无明显诱因出现腰背痛,根据症状及实验室检查误诊为脊柱关节炎,经过多学科联合诊治,最终经病理活检证实为胸椎弥漫大B细胞淋巴瘤。结论对于发病年龄大于45岁的老年患者出现腰背痛,诊断脊柱关节炎应慎重,警惕胸椎弥漫大B细胞淋巴瘤的发生。
Objective To investigate the differential diagnosis of thoracic diffuse large B cell lymphoma and spondyloarthritis. Methods One case of elderly patients with diffuse large B-cell lymphoma who had misdiagnosed as spondyloarthritis was analyzed retrospectively. Results There were no obvious causes of low back pain in patients. According to the symptoms and laboratory tests, spondyloarthritis was misdiagnosed. After multidisciplinary joint diagnosis and treatment, the final biopsy confirmed thymus diffuse large B cell lymphoma. Conclusions The diagnosis of spondyloarthritis should be considered carefully in the elderly patients with onset age above 45 years old, wary of the occurrence of diffuse large B cell lymphoma in the thoracic spine.
