Image in medicine: Cement pulmonary embolism

A 65-year-old woman was treated for vertebroplasty (cement injection). 24 hours after the procedure, she complains chest pain. A CT scan was performed which revealed on the same image section the presence of highly radiopaque material in a right basal segmental artery the density of which is strictly identical to that of the cement of the treated vertebra (yellow arrows). This cement pulmonary embolism canot be disolved by an anticoagulant treatment.
