Metallic foreign body penetrating the carotid sheath: a case report.

Foreign bodies are a common problem seen in otolaryngological practice. Of the reported foreign bodies, metallic foreign bodies are a rare entity. One of the least common complications of foreign body ingestion is penetration and migration. We describe a case of a migrating metallic foreign body in a 50-year-old woman with a history of accidental ingestion causing odynophagia. In the present case, the foreign body migrated extraluminally into the carotid sheath. Our review of literature revealed that few such cases have been reported.
