Imaging diagnosis - Equine nasal septal thickening due to chronic chondritis

Abstract

We describe the use of computed tomography (CT) in a 6-year-old mare with upper airway obstruction due to an abnormally thick nasal septum. Upon CT imaging, multifocal, expansile cyst-like lesions were detected in the nasal septum. The histopathologic diagnosis was chronic dissecting chondritis. Resection of the abnormal nasal septum resulted in resolution of the clinical signs. © Copyright 2010 by the American College of Veterinary Radiology.
