Caudal Mediastinal Abscess Due to a Grass Awn (Hordeum spp) in a Cat

Abstract

A two-and-a-half year-old male, domestic shorthaired cat was presented with a history of chronic expiratory dyspnoea, dysphagia and progressive weight loss. Thoracic radiography revealed a caudal mediastinal mass. Surgical exploration confirmed the presence of an abscess in the caudal mediastinum. Despite the good prognosis, euthanasia was performed at the owner's request and post-mortem examination revealed an abscess that had been caused by a grass awn located within.
