Myasthenia gravis (MG) is often complicated by respiratory failure, known as a myasthenic crisis. However, most of the patients who develop respiratory symptoms do so during the late course of disease and have other neurological signs and symptoms. However, in some patients respiratory failure is the initial presenting symptom. We report the case of a 68-year-old woman with MG who presented with isolated respiratory failure as her first presenting symptom. As illustrated by this case, it is important to consider neuromuscular disorders in cases of unexplained respiratory failure.
重症肌无力（MG）常伴有呼吸衰竭，称为肌无力危象。然而，大多数出现呼吸症状的患者是在疾病后期，并伴有其他神经体征和症状。然而，在一些患者中，呼吸衰竭是首发症状。我们报告了一例 68 岁女性，以孤立性呼吸衰竭为首发表现的 MG。该病例表明，对于不明原因的呼吸衰竭，应考虑神经肌肉疾病。
