CTICasesSeptic pulmonary emboli
Imaging findings
Contrast-enhanced CT shows multiple peripheral lung nodules and a giant, mobile vegetation on the pulmonic valve that subsequently embolized into the right pulmonary artery, causing main branch occlusion and hemorrhagic pulmonary infarction.
Key takeaways
Pulmonic valve endocarditis is a rare complication in intravenous drug users. Large vegetations can dislodge, embolize to the main or branch pulmonary arteries, and present as septic pulmonary emboli with secondary pulmonary infarction.
