A 4.5‐year‐old neutered female domestic shorthair cat was presented with an acute onset of neurological signs suggestive of multifocal or diffuse intracranial lesions. MRI of the head revealed bilaterally symmetrical T2‐weighted hyperintensities in the pons and thalamus, suggestive of a metabolic or toxic aetiology. The pontine lesion on MRI resembled what in humans is known as the ‘trident sign’ reported in cases of pontine myelinolysis. Ancillary cerebrospinal fluid analysis revealed albuminocytologic dissociation and suspected myelin debris. No specific cause was identified, but the cat recovered over the next few weeks with only supportive therapy.
