13 year old female neutered domestic shorthair cat with loss of voice for 6 months. Increased respiratory effort and stridor. How would you describe the lesion?
There is lobular increased soft tissue opacity in the region of the larynx. The laryngeal tissues appear narrowed, and the air column is narrowed. The soft palate is mildly thickened. Within the thorax, the cardiovascular structures are normal in size and shape. There is a moderate diffuse bronchial pattern. The pleural space and mediastinum appear normal. Small osteophytes are present in the caudal humeral heads.
- Laryngeal mass – Neoplasia (carcinoma, lymphoma), fibrosis, edema less likely.
- The bronchial pattern may be secondary to chronic lower airway disease which may have infectious and noninfectious inflammatory components.
- Mild shoulder osteoarthrosis.
