The Picture Archiving and Communication System: a useful tool in a case of upper oesophageal foreign body.

We present a case of an oesophageal foreign body (approximately 2x2 cm) which was not seen on the initial lateral soft tissue neck X-ray but was detected following manipulation of the X-ray using the Picture Archiving and Communication System of X-ray viewing. This system gives the user much greater flexibility, including a choice of magnification and contrast.
