Abstract

Although amyotrophic lateral sclerosis (ALS) does not directly affect the lung parenchyma, it can jeopardize the mechanical function of the respiratory system. About one-quarter of ALS patients have had at least one prior misdiagnosis. Therefore, a high clinical suspicion, and careful correlation of physical examination and electromyography (EMG) are needed to reach the correct diagnosis. We report a 65-year-old man who presented with a progressive exertional dyspnea. He was subsequently found to have a diaphragmatic paralysis that was felt to be secondary to spinal cord stenosis. However, his subsequent EMG showed evidence of muscle fasciculation and he was ultimately diagnosed with ALS.
