Radiological features of unusual ingested foreign bodies.

For patients who ingest foreign bodies, pre-operative radiography is an invaluable tool that allows the surgeon to confirm the presence of the foreign body, preempt potential difficulties and plan the best method for foreign body removal. This is particularly important when a foreign body is of usual shape and size. We present a series of radiographs and pictures of some of the retrieved foreign bodies of five patients who swallowed unusual foreign bodies.
