Abstract
|
|
|
|
Diffusion tensor image (DTI) can provide the prognosis of the rehabilitation as well as the structural integrity of the white matter tract in acute brain lesion. We experienced a 29-yr old female Wernicke encephalopathy patient. The extensive cerebellar lesions resulted in severe gait ataxia at the early stage of the disease. However, preserved pontocerebellar tracts which were demonstrated in 3-dimensional fiber tractography using DTI may explain the delayed improvement of gait ataxia one year later. DTI can be a useful tool for the in-vivo prediction of the ataxia prognosis in the Wernicke encephalopathy patient.
