Overlooked radiographic finding results in delayed diagnosis of a retained oesophageal foreign body.

Ingestion of foreign bodies in children is a commonly occurring event worldwide. Swallowed foreign bodies usually pass successfully through the alimentary canal, from the mouth to the anus, but occasionally they may become lodged in the lumen of the oesophagus and cause complications. Accurate diagnosis of a retained foreign body is crucial in anticipating and preventing complications, but diagnostic delay can occur. We present a case of delayed diagnosis of a foreign body ingestion in an infant. Based on our experience, we emphasise the importance of accurate interpretation of X-rays with particular attention paid to the region of highest suspicion by the first touch physician.
