CTICasesSeptic pulmonary emboli from prosthetic tricuspid valve
Imaging findings
Chest CT demonstrates a prosthetic tricuspid valve with large, mobile vegetations on the atrial side, associated with multiple bilateral, peripheral pulmonary filling defects (emboli) containing small foci of gas.
Key takeaways
Prosthetic valve endocarditis (especially on the tricuspid valve in drug users) is a common source of septic pulmonary emboli. The emboli can occasionally contain small pockets of trapped gas, indicating active infection or embolization of vegetation material.
