Presentation
Forearm bones fracture. The coin was noted on the follow-up radiograph.
Patient Data
Follow-up radiograph after forearm bones fracture. A coin was incidentally found inside the cast.
Case Discussion
The patient inserted the coin inside the cast a few days before the follow-up exam and could not remove it by himself. He did not alert his parents about the coin and had no complaints.
It is essential to identify the object correctly. While a coin is mostly harmless, a battery could injure the patient. These are very similar, but batteries usually have a slight step in profile and an inner ring when viewed across its diameter.
