Pulmonary Cement Emboli

A 66-years-old man presenting with progressive dyspnea underwent a chest CT with contrast. Reconstructed images on bone window, incidentally show hyperdense tubular structures in the right pulmonary arteries (mainly middle lobe arteries), and in the prevertebral space as well as hyperdense material in the vertebral bodies corresponding to pulmonary cement embolism and extruded cement in a prevertebral vein secondary to a vertebroplasty done 12 years ago.
