Pleural silicone granulomas result from an extremely rare situation where there is leakage of silicone from an implant rupture into the thorax.
Pathology
It is thought that scars from remote thoracotomy may provide a potential pathway for ruptured silicone to fistulise into the pleural space.
Radiographic features
FDG-PET
Mild FDG uptake in these pleural lesions may be present and attributed to surrounding granulomatous inflammation.
Differential diagnosis
They may occasionally mimic intrapulmonary metastases 1.
