Ingested foreign body: Mickey Mouse

Case contributed by Dr Laughlin Dawes


Mother concerned that a foreign body has been ingested.

Patient Data

Age: 7 years
Gender: Female

A foreign body at the level of T8. No pneumomediastinum or pneumothorax. The airway is patent. 

Case Discussion

There was no change in the position of the foreign body after 8 hours. A Mickey Mouse key ring was finally retrieved with oesophagoscopy.

Foreign body ingestion in children is a common ED presentation. If not removed, metallic/caustic material (eg, battery) can erode into oesophagus, causing ulceration or even perforation. If passed into stomach, most round FBs cause little problem.

The most common locations for FBs to lodge in the oesophagus are:

  • cricopharyngeal muscle
  • aortic knob
  • gastro-oesophageal junction.

Follow up examinations to look for passage of FBs are essential, especially if they are pointed, long, irregular or jagged.
