A 4-year-old male umbrella cockatoo (Cacatua alba) with a history of ingestion of foreign material from chewing on a household appliance presented for lethargy, inappetance, and regurgitation of 2 days duration. Foreign bodies identified on radiograph included a wire 2 cm in length in the proventriculus, a wire 3 cm in length in the ventriculus, and several pieces of rubber and plastic throughout the gastrointestinal tract. Diagnosis of a perforating ventricular foreign body was made through plain and contrast radiography. The proventricular wire was removed endoscopically but endoscopic retrieval was not successful in locating the ventricular wire. A ventriculotomy was done to remove the wire, which had perforated the ventriculus cranially and imbedded into the parenchyma of the liver. The wire was extracted from the center of a large nonresectable granuloma that incorporated the left liver lobe. The bird recovered from surgery but died from complications 3 months later. Postmortem examination revealed localized coelomitis and hepatic necrosis associated with the perforation.
