【摘要】 患者為老年男性,反復出現惡心、嘔吐、乏力、低鈉、低鉀血癥, 3次住院。對其惡心嘔吐原因,曾考慮是否有抗高血壓藥物吲噠帕胺所引起,或是老年人攝入不足,電解質紊亂所致低鈉低鉀血癥。最后考慮該患者低鈉血癥系垂體前葉功能減退所致。MRI檢查顯示空蝶鞍。空鞍的原因尚不清楚,空鞍綜合征也是垂體前葉功能減退的因素之一。此癥盡管很少見,但隨著CT、MRI這些高新設備的普遍使用及人口老齡化,會發(fā)現更多的病例,也對我們診斷治療提供了有力的依據。【Abstract】The patient’s condition: old male patient with repeat nausea, vomitus, hypodynamia, low sodium and kaliopenia. Three times to be in hospital. First, we consider that indapamide resuted low sodium and Kaliopemia,but we discovered that the anterior pituitay gland hypofunction. MRI show that empty sella turcica. The reason of empty is not clear,the saddle syndrome is also a factor of pituitary function before the leaves falling off. The disease was rare,but with common use of CT,MRI and aging,we will discover many more cases to provide power evidence for diagnosis and treatment.
