We herein report the case of a 76-year old man with aquaporin-4-Immunoglobulin-G (AQP4-IgG)-positive neuromyelitis optica spectrum disorder (NMOSD), in whom transient interstitial pulmonary lesions developed at the early stage of the disease. Chest X-ray showed multiple infiltrative shadows in both upper lung fields, and computed tomography revealed abnormal shadows distributed randomly in the lungs. Surgical lung biopsy showed features of unclassifiable interstitial pneumonia, characterized by various types of air-space organization, which resulted in obscure lung structure. This is the first report to describe the pathological findings of interstitial pneumonia, which may represent a rare extra-central nervous system complication of NMOSD.
我们在此报告一例76岁男性水通道蛋白4-免疫球蛋白G(AQP4-IgG)阳性视神经脊髓炎谱系障碍(NMOSD)患者,其在疾病早期出现了短暂性间质性肺病变。胸部X线显示双上肺野有多个浸润阴影,计算机断层扫描显示肺部有随机分布的异常阴影。手术肺活检显示为无法分类的间质性肺炎特征,表现为各种类型的气腔结构,导致肺结构模糊。这是第一份描述间质性肺炎病理结果的报告,间质性肺炎可能是NMOSD一种罕见的中枢神经系统外并发症。
