Brain MRI indings in a dog with late onset epileptic seizure after portosystemic shunt attenuation

摘要

A female Tibetan terrier aged five years and six months presented 23 months after portosystemic shunt attenuation due to generalised tonic-clonic epileptic seizure activity. Repeat MRI of the brain showed symmetrical T2-weighted hyperintense lesions affecting the cerebral grey matter bilaterally suggestive of cerebral atrophy and polioencephalomalacia. Cerebral atrophy and polioencephalomalacia could develop after successful attenuation of portosystemic shunt surgery.
