A case of tracheal avulsion with pneumomediastinum and pseudodiverticulum formation in a cat is described. Radiographs taken at initial presentation showed a pneumomediastinum with fractures of the right first to sixth ribs. Conservative treatment resolved the pneumomediastinum but following initial improvement the cat developed dyspnoea. Radiography and image intensification at this time showed a tracheal diverticulum at the level of the fourth rib. Surgical resection of the diverticulum and stenotic tracheal ends was performed via a right fourth intercostal lateral thoracotomy. The airway was maintained throughout the procedure using a bridging endotracheal tube. The cat made an unremarkable recovery following surgery.
