title: Megaesophagus in a 6-month-old cat secondary to a nasopharyngeal polyp.
abstract: A 6-month-old male domestic shorthair cat was presented for a 3-month history of dysphagia and upper respiratory signs. The cat was diagnosed with a generalized megaesophagus secondary to a large nasopharyngeal polyp that extended into the cervical esophagus. The polyp was removed by traction and a left ventral bulla osteotomy was performed to remove the polyp base. The cat's clinical signs resolved and follow-up radiographs 14 days after surgery revealed resolution of the megaesophagus. To the authors' knowledge, this is the first report of resolution of megaesophagus after removal of a nasopharyngeal polyp in a cat.
