Plain-English summary
A young Thoroughbred colt was taken to the vet because he was making unusual noises when breathing. The vet found that his nasal passages were narrowed and there was a mass in his trachea. Using special imaging techniques called ultrasonography and magnetic resonance imaging, the vet discovered that the colt had fluid-filled cyst-like structures in his nasal septum and larynx. Unfortunately, the condition was confirmed only after the colt passed away, and it was determined to be a rare birth defect.
Abstract
A foal was examined for abnormal upper airway noise. Endoscopically, there were narrowed nasal passages and an extralumenal mass of the cranial trachea. Using ultrasonography and magnetic resonance (MR) imaging of the larynx and cranial cervical trachea, irregular margins of the laryngeal cartilages and first tracheal ring containing areas consistent with fluid were identified. In MR images, a widened nasal septum was seen that contained material consistent with fluid. Postmortem examination confirmed the diagnosis of nasal septal, laryngeal, and cranial cervical tracheal cyst-like lesions. This is a unique congenital condition, in which premortem imaging was instrumental in defining the abnormalities.
