Background: Wry Nose (Campylorrhinus lateralis) is a congenital shortening and deviation of the maxillae, premaxillae, nasal bones, vomer, and nasal septum that affects mainly foals. Intrauterine positioning as an etiology of this deformity is highly unlikely. Clinically, varying degree of premaxillar deviation is noticeable upon inspection of the foals head. The deviation usually results in malocclusion, with no contact between the incisors of the mandible and maxilla. Some foals experience breathing diffi culties or have increased respiratory sounds. This condition will not self-correct, and a decision should be made to treat the foal using reconstructive techniques or to euthanize it to prevent it from suffering. The objective of this work was to describe a case of wry nose in an adult male equine.Case: A 4-year-old, 300 kg, male SRD equine was submitted for necropsy. There was no history of respiratory problems and trouble with mastication or prehension of food. Three days before death the horse showed clinical sings characterized by no ingestion of food and water, changing behavior and locomotion, weakness, and not respond to calls, seemingly oblivious to the environment evolving into permanent recumbency and death after about 24 h of the decline. The horse was treated by a veterinarian who suspected of leucoencephalomalacea. The animal died 24 h after her condition worse
