Emergency CT of abdominal complications of ingested fish bones: what not to miss.

Fish bones are the most commonly ingested structures and the most common cause of foreign body perforation of the gastrointestinal tract (GIT).

Besides, patients commonly do not refer that a fish bone was swallowed.
