Аннотация
A 49-year-old woman presented with abdominal distention and right leg numbness. Bone biopsy from a huge tumor in her pelvis revealed chondrosarcoma, and proton beam therapy was performed. Although there were no abnormalities at 6 months, dry cough, dyspnea and fever with elevated inflammation appeared at 9 months. Computed tomography showed multiple consolidations in both lungs, different from typical images of nodular shadows with calcification in pulmonary metastases of chondrosarcoma. We first suspected infection or organizing pneumonia, but biopsy revealed chondrosarcoma metastases with severely infiltrated inflammatory cells. Imaging patterns we experienced may reflect inflammatory pathogenesis due to rapid cancer progression.
