Case summary A 7-year-old male neutered domestic shorthair cat was presented with a 3-month history of dyspnea when exercising and increased respiratory noise when purring. Initial radiographs identified a suspected laryngeal mass. Point-of-care ultrasound found a fluid-filled structure on the larynx, which was drained percutaneously. The cat initially recovered well but, due to recurrence of clinical signs, a CT scan was performed, which confirmed the presence of a laryngeal cyst that was subsequently surgically resected. Histopathological analysis was consistent with a suspected thyroglossal cyst. Relevance and novel information This is only the second report of a laryngeal cyst in the cat. While malignant laryngeal disease may be more prevalent in the cat, benign differentials should be considered as treatment could be curative, as was observed in this case.
