[Bullet embolism in a case of homicide: case report].

INTRODUCTION
Bullet embolism is a special form of embolism, where embolus is either a bullet or its fragment. Bullet penetrates through the injured part of the body into circulation and then travels to a distant part of the body, until it gets blocked in a vessel of the same diameter as the bullet.


CASE OUTLINE
We are presenting a case of gunshot injury in a 26-year-old male, found unconscious on the passenger seat, with the gunshot injury of the right hand and hemithorax, who died two hours after admission to hospital. Post-mortem X-ray revealed the presence of a metallic foreign body - a bullet, in the level of the left femoral neck. The autopsy revealed entrance and exit gunshot wounds of the upper third of the right upper arm.There was a second entrance gunshot wound, and the bullet passed through the right hemithorax and the right lung, and then through the intervertebral disc between the eighth and ninth thoracic vertebrae, and also making a complete laceration of the wall of the thoracic aorta, in the right posterior semicircumference. The slightly deformed bullet, caliber 7.65 mm, was found embedded in the lumen of the vessel at the bifurcation of the deep femoral artery from the left femoral artery.


CONCLUSION
Bullet embolism is a rare complication of gunshot wounds. It should be suspected in any gunshot wound victim without an exit wound, or the lack of a missile in the bullet pathway, or if there are premortem signs or symptoms unexpected for the presumed pathway of the bullet, such as distant ischemia or infection. In these cases, some of postmortem imaging techniques should be used to save time in diagnosis, treatment and at autopsy.
