A 60-year-old nonsmoking woman presented with hemoptysis. Chest radiograph showed a diffuse reticulonodular shadow (Picture 1), and thoracic computed tomography demonstrated diffuse thin-walled cysts, with multiple nodular shadows and ground glass opacities, in both lung fields (Picture 2). Fluorodeoxyglucose (FDG)-positron emission tomography revealed an 8-cm tumor in the left iliac bone (Picture 3), which was histologically diagnosed as angiosarcoma. The uptake of FDG was also observed in multiple lung nodules (Picture 4). Diffuse cystic lung diseases can be
