Diagnosis: Cement embolus. Note the several thin linear densities in the right mid-lung (Figure 2). These represent vertebroplasty cement particles that have embolized into distal pulmonary artery branches. Patients are usually asymptomatic, and treatment is supportive, though some require anticoagulation or embolectomy. Most cases resolve within 1 year. Computed tomography chest x-rays should be obtained to rule out cardiac complications, including perforation.
