摘要：

Magnetic resonance imaging (MRI) findings associated with chronic liver disease are characterized by cerebral atrophy and bilateral, symmetric hyperintensities of the globus pallidus on T1-weighted images without corresponding signal intensities in T2-weighted images. Recently, distinct MRI changes of acute hepatic encephalopathy have been described which may be misinterpreted given their resemblance to hypoxic-ischemic injury imaging changes as well as their limited description in the neurologic literature. We describe 3 cases of acute hyperammonemic encephalopathy primarily characterized by restricted diffusion involving the insular and cingulate cortices and thalamus bilaterally.
