CTICasesCement pulmonary embolism
Imaging findings
Fluoroscopy and chest CT show leakage of dense bone cement from a thoracic vertebral body into the azygos vein and subsequent migration into the right pulmonary artery, appearing on CT as a dense, coiled, radio-opaque string-like structure.
Key takeaways
Cement pulmonary embolism is a known complication of vertebroplasty, occurring when liquid bone cement leaks into the vertebral venous plexus and embolizes to the lungs. It can present on chest CT as highly radio-opaque linear or coiled structures within the pulmonary arteries.
