A 3 year girl with epilepsy and moderate learning difficulties attended for magnetic resonance imaging. Anaesthesia involved breathing sevoflurane via a laryngeal mask airway. The localiser magnetic resonance image was unobtainable owing to large apparent metallic artefact, despite no relevant history provided. On waking, she coughed out a coin, and subsequent imaging was satisfactory. Her parents then remembered that she had attended her local hospital after a choking spell three months earlier. She had not received a radiograph. Unexplained metallic artefacts occur only rarely in children, and a detailed clinical history is essential before magnetic resonance imaging.
