An adult female Moluccan cockatoo (Cacatua moluccensis) was evaluated for a 10-day history of progressive ataxia and weakness. The bird had been exposed intermittently over a 3-day period to a cage that had previously housed juvenile raccoons. Results of diagnostic tests were inconclusive and, despite supportive care, the bird died 7 days after the initial presentation. Histopathologic examination revealed a single nematode larva in the midbrain that was consistent with Baylisascaris species and multifocal granulomas in the left ventricle of the heart. The neurologic disease in this bird was attributed to encephalitis caused by neural larval migration of the raccoon roundworm, Baylisascaris procyonis.
