Sleep-related breathing disorders have been extensively reported as a frequent and major problem in patients with multiple system atrophy (MSA). Laryngeal stridor and obstructive sleep apnea are the most common sleep disordered breathing in MSA. We report laryngeal stridor in a patient with multiple system atrophy. A 56-year-old man presented with abnormal breathing sound different from snoring during sleep noticed by his bed partner. He is unaware of his nocturnal stridor. Polysomnography showed obstructive sleep apnea and laryngeal stridor. Laryngoscopy during wakefulness detects normal movement of vocal cord. CPAP (continuous positive airway pressure) eliminated laryngeal stridor and obstructive sleep apnea with pressures of 9 cmH2O.
