Air-powered rifles shoot ball bearings with enough kinetic energy to penetrate skin and fracture underlying bones. In addition, there are reports of these ball bearings embolizing within the vascular network, causing serious injuries such as ischemic stroke with resultant blindness. The severity of these complications warrants occasional removal of these foreign bodies; however, they can be difficult to localize. In this case report, we describe the use of a magnetic port finder, a sterilizable tool used in breast reconstruction, to localize the foreign body in situ. We believe that this tool is effective at locating ferrous foreign bodies precisely, allowing for surgical retrieval while minimizing damage to surrounding tissue.
