What is Your Diagnosis?

A 3-month-old, sexually intact male domestic goose (Anser anser) was presented to the Louisiana State University Veterinary Teaching Hospital (Baton Rouge, LA, USA) with a 2-day history of progressive lethargy, anorexia, and neurologic signs. The neurologic signs observed by the owner consisted of intermittent circling, stargazing, and neck tremors occurring 4–5 times daily with normal, mentally appropriate behavior noted between episodes. The goose was housed outdoors in a shared enclosure with 1 other goose and 7 ducks. A separate enclosure that contained 12 chickens was also on the property but was not in direct contact with the ducks and geese. Over the past 3–4 weeks, several of the ducks were presented to the primary veterinarian with similar clinical signs. All the ducks died or were humanely euthanized following treatment based on their clinical condition. Additional diagnostic testing and postmortem examination of the ducks were not performed. On physical examination, the goose was depressed, with a thin body condition score (3/9), and weighed 3.1 kg. A bilateral serous discharge from the nares was present, and the goose had a mildly increased respiratory effort with an intermittent cough during examination. On neurologic evaluation, the goose ambulated with an intoed and ataxic gait and intermittently stargazed and walked into corners. The patient also displayed intention tremors of the head and neck and maintained the neck in a retracted position throughout the examination. A small volume of watery green diarrhea was also noted, although the remainder of the physical examination was unremarkable. A blood sample was collected for a complete blood count (CBC) and plasma biochemistry profile. Results of the CBC revealed a packed cell volume of 37% (reference interval 38–58%), and the only abnormality in the plasma biochemistry panel was an increased gamma-glutamyl transferase of 15 U/L (reference 0–5 U/L). Full-body radiographic imaging was performed and revealed numerous pinpoint mineral opacities within the ventriculus consistent with grit. Overall, there were no significant radiographic findings on the images obtained of the patient. Additional blood and fecal samples were acquired for heavy metal testing (lead and zinc); viral disease testing, including eastern equine encephalitis (EEE) and West Nile virus (WNV) serology; and a fecal direct examination and flotation.
