Nigri GR et al. - We report a case of a 36-year-old man who was admitted to the Emergency Department with right flank pain. The clinical presentation was suggestive of renal colic. However, a computed tomography scan showed the presence of a foreign body in the inferior duodenal flexure. When evaluating patients with acute abdominal pain, foreign body ingestion should be considered. In patients with a history of toothpick ingestion, immediate diagnosis with endoscopic management should be performed.
