An adult Bichon Frise first presented, aged 9 years, with seizures. CSF, bloods and MRI at initial presentation were all said to be normal and the dog responded well to medical treatment.

On this occasion an ill-defined area of T2W hyperintensity was found in the ventral aspect of the right temporal lobe and hippocampus with corresponding T1W hypointensity.
