Hyponatraemia is the most common fluid-electrolyte disorder, and the most frequent related aetiologies are syndrome of inappropriate secretion of antidiuretic hormone (SIADH), which accounts for up to 38%. SIADH has been linked to multiple pathologies that affect the central nervous system; these disorders generally originate in the brain and, more rarely, in the spinal cord. It is often observed in patients undergoing neurosurgery and in patients with head injuries or intracranial tumours, and less common in those with spinal pathologies, especially traumatic. We describe an SIADH case associated with syringomyelia, in a patient admitted for severe, symptomatic hyponatraemia.
低钠血症是最常见的液体电解质紊乱，最常见的相关病因是抗利尿激素分泌不当综合征（SIADH），其占比高达38%。SIADH与多种影响中枢神经系统的病理状况有关；这些疾病通常起源于脑部，较少起源于脊髓。在接受神经外科手术的患者以及头部受伤或患有颅内肿瘤的患者中经常观察到，而在患有脊髓疾病（尤其是创伤性疾病）的患者中较少见。我们描述了一例与脊髓空洞症相关的SIADH病例，该患者因严重的症状性低钠血症入院。
