Foreign body (FB) ingestion is a relatively common reason for visits to the emergency room. If the FB is symptomatic or damaging to the patient, either endoscopic or surgical intervention should ensue. We present a case of abdominal pain and hematuria beginning ∼24 h after an incidental FB ingestion. Initial CT imaging defined a linear opacity perforating through the posterior duodenal wall abutting the ureter causing inflammation and hydronephrosis. After two unsuccessful endoscopic attempts at retrieval, we were able to identify the object with the aid of intraoperative fluoroscopy and surgically remove the FB. The patient recovered uneventfully and was discharged home. Posterior duodenal perforation by an FB may not manifest with obvious localized or systemic symptoms unless the perforation involves surrounding structures such as the aorta, vena cava or ureter. In such cases, surgical intervention is required for FB removal.
