Furthermore the lungs serve as the most frequent sites for metastases. Pulmonary metastases from sarcomas usually appear as round nodules of varying sizes on roentgenograms. Here we report an unusual clinical and radiographic presentation of pulmonary metastasis from a costal chondrosarcoma. Bilateral pulmonary metastases developed soon after wide surgical resection. Thoracic computed tomography revealed unusual radiological findings consolidation accompanied with ground-glass opacity. To confirm the metastasis we recommend a transbronchial biopsy in cases where unusual pulmonary findings are detected. Background Chondrosarcomas are the second most frequent primary malignant bone tumors after osteosarcomas 1 2 . They are also the most common primary malignant chest wall tumors 5-15 of chondrosarcomas are located in the thoracic wall 3 . Since radiotherapy and chemotherapy are generally ineffective against chondrosarcomas surgery is the only curative treatment and the quality of the surgery is an essential prognostic factor 2 .
