Fig 3. A, Transverse T2-weighted fast FLAIR images obtained in a patient with liver cirrhosis during an episode of hepatic encephalopathy. Observe the symmetric areas of increased signal intensity along the corticospinal tract in both cerebral hemispheres. B, This signal-intensity abnormality almost completely reverses on a follow-up study obtained few months later, when the patient showed no signs of overt hepatic encephalopathy.
