Abstract
BackgroundOvine laryngeal chondritis is a rare entity of sheep in the USA, Great Britain, New Zealand and Iceland, but has not been reported in Germany so far. Here, two German cases are reported.Case presentationTwo rams showed severe and progressive signs of dyspnea. Endoscopically, a severe bilateral swelling of the larynx was identified in both rams. Due to poor prognosis and progression of clinical signs one ram was euthanized, while the other ram died overnight. In both cases, a necrosuppurative laryngitis and chondritis of arytenoid cartilages was found at necropsy. Fusobacterium necrophorum and Streptococcus ovis were isolated from the laryngeal lesion in one animal.ConclusionsThis is the first report of ovine laryngeal chondritis in continental Europe. This entity should be considered a differential diagnosis for upper airway disease in sheep.

Summary
Ovine laryngeal chondritis is a rare entity of sheep in the USA, Great Britain, New Zealand and Iceland, but has not been reported in Germany so far. Ovine laryngeal chondritis is characterized by chronic inflammatory changes of the arytenoid cartilages [5]. Case presentation Two rams (cases 1 and 2) were referred to the Clinic of Swine, Small Ruminants and Forensic Medicine of the University of Veterinary Medicine Hannover, Foundation, Germany due to severe respiratory problems in October 2017 and February 2019, respectively. A severe bilateral symmetric swelling of the larynx with obstruction of the laryngeal cavity was observed in the first ram (Fig. 1a).
