Central vestibular disease associated with Horner’s syndrome in a kitten

Abstract

A 45-day old female domestic short-haired (DSH) cat was referred due to lack of balance. Its history was unknown but clinical examination showed delayed postural reactions on the right-side limbs. Right eye menace reflex was absent but pupillary light reflex (PLR) was normal. Also, there was obvious miosis, third eyelid protrusion, and decreased palpebral fissure in the right eye. The cat became wasted and died the next day. At necropsy there were no visible gross lesions in any organ. Microscopically, hemorrhagic foci were observed in the cerebrum and cerebellum. Based on the symptoms and central vestibular system lesions, a diagnosis of Horner\\'s syndrome on the right side was postulated.
