Unusual bullet embolism in the brachial artery: Case report and literature review.

Chest cardio-vascular trauma by a gunshot bullet is less common than head trauma in forensic medicine practice, but still an extremely mortal injury. In front of no exit wound, ballistic trajectory could appear unexplained. We present the case of a 43-year-old man who sustained a gunshot wound in his chest. The entrance was facing the sternum and there was no exit wound. An autopsy completed by forensic radiology (CT-scan of the whole body) showed a wound of anterior pericardial, massive bleeding of pericardia, a wound of the anterior ascending thoracic aorta, and then the bullet embolism to the left brachial artery. Without forensic imaging, the bullet was difficult to find. Bullet embolization should be suspected when there is a gunshot injury to the chest without an exit injury and with no projectile in the area, particularly if the projectile is small. Forensic radiology can help to find bullet projectile: by using whole-body radiography or computed tomography.
