ABSTRACT: Approximately 13,500 children each year are treated for non-powder gun injuries of which approximately one-quarter of these injuries are puncture wounds. Although rare, vascular migration of the bullet or pellet (otherwise known as the “wandering bullet”) may result in downstream organ damage secondary to vascular or venous occlusion, most commonly travelling anterograde and lodging within the lung venous system. Interestingly, we present a case of a 12-year-old female who was shot in the neck with a compressed-air gun loaded with ball-bearing pellets. Eventual retrograde vascular migration of the ball-bearing pellet from the right internal jugular vein to the hepatic vein caused hepatic venous occlusion and congestion. It is important for radiologists to remember the possibility of retrograde travel of bullets and pellets, and radiographs should be scrutinized for foreign bodies present in areas other than the region of injury. Bullet retrieval is determined by clinical evaluation and necessity, and if indicated, endovascular, percutaneous retrieval, or surgical exploration may be considered.
