An 11-week-old Holstein heifer calf was presented to the Cornell University Hospital for Animals Internal Medicine Service for evaluation of stridor of approximately five days duration, which had begun following an episode of pneumonia. Clinical signs of stridor, inspiratory dyspnea, fever, and cough, in combination with laryngeal endoscopy, confirmed a diagnosis of necrotic laryngitis. Medical management with oxytetracycline, procaine penicillin G, and nebulization with albuterol and acetylcysteine was attempted for seven days, after which improvement was determined to be minimal. Subsequently, a laryngotomy and unilateral right partial arytenoidectomy were performed. The calf recovered without complications and continues to do well living on the farm.
