RESUMO
Background: The wing-beating tremor, characteristic of Wilson's disease (WD), is a disabling symptom that can be resistant to anti-copper and anti-tremor medications. Phenomenology Shown: This video illustrates severe bilateral wing-beating tremor, moderate head and lower limb tremors, mild cervical dystonia, and subtle cerebellar ataxia, with nearly resolution after penicillamine treatment. Educational Value: This case highlights a typical aspect of WD, emphasizing the importance of early detection and treatment, and its correlation with MRI findings. Highlights: This case highlights the typical wing-beating tremor in Wilson's disease and its correlation with the involvement of the dentato-rubro-thalamic pathway. The early diagnosis and initiation of treatment with penicillamine resulted in an excellent clinical and radiological response.
