Pseudohyponatremia is an often misdiagnosed condition that needs to be managed by addressing the underlying cause. Treatment of hyponatremic patients with intravenous fluids without ruling out pseudohyponatremia may aggravate a patient's hyponatremia and result in adverse outcomes. In a patient whose sodium is deteriorating, it is critical to diagnose pseudohyponatremia early in the course and acquire necessary consultations, even if the patient is asymptomatic. We discuss a case of a man in his 20s with a history of liver transplantation who presented with unexplained dangerously low sodium while being asymptomatic. The case illustrates an uncommon cause of pseudohyponatremia due to lipoprotein-X hypercholesterolemia in a patient with cholestatic liver disease.
假性低钠血症是一种常被误诊的病症，需要针对潜在病因进行处理。在未排除假性低钠血症的情况下，用静脉输液治疗低钠血症患者可能会加重患者的低钠血症并导致不良后果。对于血钠水平正在恶化的患者，即使患者无症状，在病程早期诊断假性低钠血症并进行必要的会诊至关重要。我们讨论一例20多岁有肝移植病史的男性病例，该患者无症状，但出现了原因不明的危险低血钠情况。该病例说明了胆汁淤积性肝病患者中脂蛋白-X高胆固醇血症导致假性低钠血症的一种罕见原因。
