Ruptured pulmonary infarct
Imaging findings
Contrast-enhanced CT shows thromboembolism in the right lower lobe pulmonary artery with an adjacent peripheral pulmonary infarct that subsequently cavitated, ruptured into the pleural space, and developed a bronchopleural fistula and empyema.
Key takeaways
Pulmonary infarction is a vascular complication of pulmonary embolism. Rarely, an infarct can undergo aseptic cavitation and rupture into the pleural space, creating a bronchopleural fistula and secondary empyema.
