Hépatopathies chroniques et hypersignaux spontanés T1Â en IRM cérébrale

Brain MRI abnormalities, especially on T1 sequences and cerebral atrophy, have been reported in patients with chronic liver disease. These high-intensity T1 signals arise from manganese deposits in the basal ganglia observed in liver diseases. They may have diagnostic value for subclinical liver disease. We report two cases of liver disease where the diagnosis was suggested by the MRI abnormalities and confirmed after further explorations.
