CTICasesRight Ventricular and Pulmonary Shotgun Pellet Embolization
Imaging findings
Chest radiograph and CT demonstrate multiple small, metallic shotgun pellets located within the right ventricle and branching vessels of the pulmonary arterial tree. No entry wounds are present on the chest wall.
Key takeaways
Gunshot and shotgun injuries to the pelvis or extremities can lead to pellet embolization via the systemic venous circulation (such as gonadal or iliac veins) to the right heart and pulmonary arteries. Finding metallic fragments in the chest of a trauma patient without local thoracic injury should prompt an evaluation for a distant entry site and venous embolization.
