Copper Conundrum: Navigating Atypical Wilson's Disease Through Radiological Insights

Area of Science:

• Neurology
• Genetics
• Metabolic Disorders

Background:

• Wilson's disease is a rare autosomal recessive genetic disorder caused by mutations in the ATP7B gene, leading to impaired copper excretion and accumulation in organs.
• Abnormal copper metabolism in Wilson's disease can result in significant neurological and hepatic manifestations.

Observation:

• A 14-year-old male presented with severe generalized dystonia, rigidity, myoclonic jerks, dysarthria, and excessive salivation.
• Ophthalmic examination revealed Kayser-Fleischer rings.
• Brain MRI demonstrated symmetrical cortical and subcortical hyperintensities, particularly in the basal ganglia and brainstem, with diffusion restriction in the fronto-parietal regions.

Findings:

• Diagnosis was confirmed via low serum ceruloplasmin and elevated urine copper excretion.
• Neurological symptoms included dystonia, rigidity, and dysarthria.
• Atypical MRI findings, including diffusion restriction, were noted.

Implications:

• This case highlights the importance of recognizing unusual brain MRI findings in Wilson's disease for timely diagnosis.
• Early and appropriate management, including penicillamine and supportive care, can lead to partial recovery.
• Identifying atypical presentations is key to preventing irreversible neurological damage in Wilson's disease.
