Multiple system atrophy (MSA) is a neurodegenerative disorder characterized by Parkinsonism, cerebellar ataxia, and autonomic dysfunction. While less frequent than Parkinson's disease, MSA patients with a beneficial levodopa response may occasionally present with levodopa-induced dyskinesia (LID). We herein report a 50-year-old woman diagnosed with MSA-parkinsonism who developed LID in the unilateral lower extremity 10 months after the start of levodopa treatment. In this case, the distribution of LID, the timing of its onset, and the presence of LID despite relatively poor levodopa responsiveness were distinctive.
