Plain-English summary
A 12-day-old Arabian foal was brought in with a swelling on the right side of its neck that had been present since birth. After imaging tests, the veterinarians found a cystic mass connected to the trachea, which was causing the swelling. The foal underwent surgery to remove the mass, and a follow-up examination showed that it had a congenital tracheal diverticulum, which is a rare condition. Fortunately, the foal recovered well after surgery, and there were no significant scars after 40 days.

Abstract
Tracheal congenital defects are infrequent but serious findings in animals. Tracheal diverticula are congenital air-filled cystic lesions, a sub-type of paratracheal air cyst mainly found extra-thoracically in foals. We describe a case in a twelve-day old show Arabian colt with right sided unilateral cervical swelling since birth. Percutaneous ultrasound revealed a heterogeneously air- and fluid-filled spheroid mass, and upper airway endoscopy confirmed luminal communication to the trachea. Contrasted computed tomography showed a narrow isthmus originating between two proximal tracheal rings and coursing caudally before dilating to form the palpable mass, and facilitated detailed surgical planning. The mass was excised completely under general anesthesia. Histopathological examination confirmed a congenital tracheal diverticulum with pseudostratified columnar epithelial walls, milk-like content and secondary intramural bacterial infection. The foal´s recovery post-surgery was favorable, and resolution was complete with minimal scarring 40 days following discharge. This case illustrates appropriate diagnostic approach and intervention in a rare case of congenital disease.
