This report describes unusual diffusion and proton spectroscopic magnetic resonance (MR) imaging findings in a 12-year-old boy with WD who presented with hemichorea and subnormal copper metabolism. The MR imaging findings of lactate accumulation, decrease of N-acerylaspartate/creatinine (NAA/Cr) ratio and markedly increased apparent diffusion coefficient (ADC) value of the asymmetrical edematous putaminal lesions in the early stage were suggestive of acute necrosis with anaerobic metabolism of glucose leading to poor clinical outcome at follow-up.copper; article; case report; child; demyelinating disease; human; male; metabolism; necrosis; nuclear magnetic resonance imaging; nuclear magnetic resonance spectroscopy; pathology; putamen; Wilson disease; Child; Copper; Demyelinating Diseases; Hepatolenticular Degeneration; Humans; Magnetic Resonance Imaging; Magnetic Resonance Spectroscopy; Male; Necrosis; Putamenjournal article10.1007/s00234-004-1306-z2-s2.0-33644804878
