"Common pleural masses include:"
"Extrapleural causes can arise from components of the chest wall, including bone/cartilage, nerves, vasculature, fat, muscle, and skin. If there is a sign of rib/bone involvement on the chest radiograph the lesion is most likely to be extrapleural. In adults, skeletal metastases are the most common chest wall malignancy while chondrosarcoma is the most common primary malignant tumour."
