Megaesophagus in an 8-month-old cat secondary to a laryngomucocele

An 8-month-old spayed female cat presented with a 7-week history of progressive dyspnoea, dysphagia and regurgitation. Plain radiography revealed megaoesophagus with a large, rounded, soft tissue opacity laryngeal mass. Endoscopic examination revealed a fluid-filled lesion, which was lanced and drained completely. As a result of recurrence of the mass and infection 2 days later, the mass was surgically excised. The mass was diagnosed as a laryngomucocele based on clinical and histopathological findings. Clinical signs resolved immediately after removal of the mass, the megaoesophagus resolved a couple of days postoperatively and no relapse was noted over the following 3 years.
