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.
