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

To the author's knowledge, this is the first case of laryngomucocele described in a cat. This cause should be included in the differential diagnosis of respiratory obstruction and acquired megaoesophagus in cats. This report demonstrates that megaoesophagus resulting from a respiratory obstruction resolves spontaneously after removal of the obstruction; therefore, respiratory tract assessment should be recommended in cats with signs of megaoesophagus because the prognosis could be good compared with other causes of megaoesophagus.
