On the bone windows (1st stack) multiple curvilinear high-density deposits causing filling defects are seen throughout the lower lobe segmental and subsegmental pulmonary arteries bilaterally.
Features consistent with acrylic cement emboli post vertebroplasty. The vertical linear high density adjacent to the T9 vertebra represents cement extravasation in a paravertebral vein.
On the arterial soft tissue window (second stack) the high-density in the right lower lobe segmental pulmonary artery is associated with surrounding clot formation proximally.
Other findings:
Left pleural effusion with associated atelectasis. Left mastectomy. Surgical clips within the left axilla. Lytic appearance to posterior left second rib, sclerotic anterior left third rib.
Background:
Metastatic left breast cancer, managed with mastectomy and left axillary lymph node dissection followed by chemoradiation.
Recurrence with T10-L3 pathological fractures and canal stenosis requiring lumbar L3/L4 percutaneous stabilisation, T10 corpectomy and fusion.
