CTICasesIntracardiac Shotgun Pellet Embolus
Imaging findings
CT chest in a trauma patient shows a single, dense metallic shotgun pellet lodged within the right ventricle, without local myocardial injury or hematoma, following a shotgun wound to the lower extremity.
Key takeaways
Bullet or pellet embolization occurs when a projectile enters the venous system and embolizes to the right side of the heart or pulmonary arteries. Patients can remain asymptomatic, and the pellet is often discovered incidentally. Management is typically conservative unless the foreign body causes tricuspid valve dysfunction, arrhythmias, or septal perforation.
