Plain-English summary
A 6-month-old male domestic shorthair cat was brought to the vet because he was unable to make sounds, was vomiting, regurgitating, and had a runny nose along with breathing issues. X-rays showed he had a condition called megaesophagus, where the esophagus is enlarged, and further tests revealed a large mass in his throat that was blocking his airway. The vet performed surgery to remove the mass, which was identified as a nasopharyngeal polyp (a growth in the throat). After the surgery, the cat's symptoms improved, and he was reported to be doing well three years later.

Abstract
A 6-month-old intact male domestic shorthair cat presented with a history of aphonia, vomiting, regurgitation, chronic purulent nasal discharge, and recurrent signs of respiratory infection. Radiographic examination revealed alveolar lung pattern and generalized megaesophagus at the thoracic and caudal cervical region. Additional examinations by computed tomography and virtual tracheoscopy revealed a large mass on the nasopharyngeal area that occupied about 90% of the tracheal lumen. With the aid of tracheostomy, the mass was removed with traction and sharp excision. According to histopathological findings the mass was diagnosed as nasopharyngeal polyp. A recheck examination performed a week later and the clinical manifestations of the megaesophagus were resolved and also three years later during a phone call, his owner reported he was doing well. To the best of the knowledge of the authors, megaesophagus following nasopharyngeal polyp is only reported in three other cats.
