    A five-year-old, entire, male dachshund was presented with a five day history of hypersalivation and regurgitation as well as polyuria and polydipsia for several months. Chest radiographs demonstrated megaoesophagus and aspiration pneumonia. Furthermore, hyperadrenocorticism was demonstrated by means of elevations in levels of serum alkaline phosphatase and cholesterol, decreased urinary specific gravity, increased response to adrenocorticotropic hormone stimulation, insufficient suppression of the post-dexamethasone plasma cortisol levels, an increased endogenous adrenocorticotropic hormone concentration and bilaterally enlarged adrenal glands on abdominal ultrasound. The dog became severely dyspnoeic and was euthanased after magnetic resonance imaging was performed. The magnetic resonance imaging and necropsy revealed the sellar region mainly filled with fluid, with only small tissue remnants, a condition defined as empty sella syndrome in human medicine. To the author's knowledge, this is the first dog described with empty sella syndrome and only the second dog described with hyperadrenocorticism secondary to ectopic adrenocorticotropic hormone production. However, the association between empty sella syndrome and hyperadrenocorticism may be no more than incidental.
