Paraneoplastic neurological syndrome (PNS) is a heterogeneous group of neurological disorders caused by immune-mediated inflammatory mechanisms. We herein report a 77-year-old man with CV2/CRMP5-antibody-related PNS associated with a gastrointestinal stromal tumor (GIST). He was admitted for forgetfulness and delusional behavior. His neurological symptoms were subacute, and a whole-body examination revealed a gastric GIST. Serology showed CV2/collapsin response mediator protein (CRMP)-5 antibodies. Partial gastrectomy was performed for the GIST, and the neurological symptoms and serum CV2/CRMP5 antibodies disappeared. No relapse has occurred since the surgery. PNS should be considered in patients with subacute neurological disorders.
副肿瘤性神经系统综合征（PNS）是一组由免疫介导的炎症机制引起的异质性神经系统疾病。我们在此报告一名77岁男性，患有与胃肠道间质瘤（GIST）相关的CV2/CRMP5抗体相关PNS。他因健忘和妄想行为入院。他的神经系统症状呈亚急性，全身检查发现胃GIST。血清学检查显示CV2/塌陷反应介导蛋白（CRMP）-5抗体。对GIST进行了部分胃切除术，神经系统症状和血清CV2/CRMP5抗体消失。术后未再复发。对于患有亚急性神经系统疾病的患者，应考虑PNS。
