title: Diagnostic imaging of peripheral vestibular disease in a Chinese goose (Anser cygnoides).
abstract: A 20-year-old Chinese goose (Anser cygnoides) presented for severe left-sided head tilt and circling to the left. Peripheral vestibular disease associated with otitis media extending into the left quadrate bone was diagnosed by magnetic resonance imaging and computed tomography. Otoscopy confirmed a ruptured tympanic membrane, and a brainstem auditory evoked response test confirmed loss of hearing in the affected ear. Surgery to remove the caseous material and long-term medical therapy improved the bird's head tilt and quality of life. Otitis, hearing loss, and vestibular disease are rare in birds but can be managed after appropriate investigation. This is the first reported use of multiple advanced diagnostic tests and successful treatment of vestibular disease in a goose.
