摘　　要：1病例报告 患者,男,48岁,以＂腰痛5个月余＂为主诉于2012年2月来我院就诊。影像学诊断为腰椎间盘突出症。有高血压病史2年,服用左旋氨氯地平及氯沙坦钾片降压治疗,血压控制在130/80 mmHg（1mmHg=0.133kPa）。住院期间常规检查发现低钠血症,血钠124 mmol/L。患者自诉因高血压而长期严格低钠饮食,即予正常饮食并常规补钠治疗,其后多次复查电解质,提示血钠进行性下降,最低至120mmol／L，血浆渗透压670．5kPa（260mOsm）。Clinical records of a patient with olfactory neuroblastoma presented with hyponatremia as initial symptoms were analyzed and the literatures were reviewed.At initial onset,the patient presented with hyponatremia.After pathological examination,the diagnosis was olfactory neuroblastoma.The blood sodium has been normal after operation and radiotherapy.The incidence rate of olfactory neuroblastoma is low,and it is easily misdiagnosed.Its diagnosis relies on pathological examination.We should pay more attention to the unspecific symptoms of patients with hyponatremia,which can help to improve early diagnosis and the prognosis.
