Myasthenia gravis (MG) classically presents with ocular, bulbar, and predominantly proximal muscle weakness. Isolated bulbar symptoms occur in less than 25% of cases and can mimic stroke (1-3). If left untreated, MG can lead to significant morbidity and mortality, including myasthenic crisis and recurrent aspiration pneumonia. We describe a case of a 68-year-old man who presented with isolated bulbar symptoms. We used a novel approach to diagnosis which included a videofluorographic swallow study with concomitant Tensilon (edrophonium) injection.
重症肌无力（MG）的典型表现为眼部、延髓部以及主要是近端肌肉无力。孤立的延髓部症状在不到25%的病例中出现，且可能类似中风（1 - 3）。如果不进行治疗，MG可导致严重的发病和死亡，包括重症肌无力危象和反复吸入性肺炎。我们描述了一例68岁男性患者，其表现为孤立的延髓部症状。我们采用了一种新颖的诊断方法，其中包括进行电视透视吞咽研究并同时注射腾喜龙（依酚氯铵）。
