CTICasesInfective endocarditis
Imaging findings
Contrast-enhanced CT in an intravenous drug user shows multiple peripheral pulmonary nodules (septic emboli) and a giant vegetation on the pulmonic valve, associated with a retained metallic needle fragment in an adjacent vein.
Key takeaways
Right-sided infective endocarditis primarily affects intravenous drug users. The presence of retained metallic needle fragments in peripheral veins is a direct diagnostic clue to intravenous drug abuse, and massive vegetations can lead to recurrent septic emboli.
