  1. Radiopaque linear density overlying the right hilum, concerning for cement embolization. Further evaluation with CT chest without contrast is recommended.
  2. Right upper lobe calcific density, which may represent a calcified granuloma or additional cement embolization.
  3. Thoracic vertebroplasty.
  4. Dense mitral valve annular calcification.

2 high density structures in the right upper lobe is likely cement based on the cement in the paravertebral  veins also.Cement leak into the paravertebral veins can lead to pulmonary cement embolism.

Case Discussion

This is likely chronic and nothing to do now. Cement embolism is a well known complication of vertebroplasty. One should know of this procedure and complication when reading radiographs.
