Abstract

A 7-year-old and a 10-year-old Congo African grey parrot (Psittacus erithacus erithacus; parrots 1 and 2, respectively) were evaluated because of neurologic deficits.

Parrot 2 had a 6-month history of decreased activity and vocalizing, with an extended history of excessive water intake; a water deprivation test ruled out diabetes insipidus, and psychogenic polydipsia was suspected. Both birds had ophthalmologic asymmetry, with anisocoria detected in parrot 1 and unilateral blindness in parrot 2. Metal gastrointestinal foreign bodies were observed on whole-body radiographs of both birds, but blood lead concentrations were below the range indicated for lead toxicosis. Findings on CT of the head were consistent with hydrocephalus in both cases. Parrot 1 received supportive care and died 3 months after the diagnosis of hydrocephalus. Parrot 2 was treated with omeprazole and prednisolone for 10 days without any improvement in neurologic deficits; euthanasia was elected, and hydrocephalus was confirmed on necropsy. No underlying or concurrent disease was identified. Hydrocephalus should be considered a differential diagnosis ...Continue Reading
