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?
Findings
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.
Differential Diagnosis
- 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.
Diagnosis
CT showed a poorly enhancing mass of the left retropharyngeal wall. An endoscopic examination with biopsy of the mass revealed large cell lymphoma. An additional mass was found at the ileocolic junction. The patient responded to chemotherapy well with relapse after 8 months.
