We present a case of pulmonary carcinosarcoma. The patient is a 31-year-old man with a history of infectious mononucleosis in whom a right lung mass was found. His age is lower than the mean age at which pulmonary carcinosarcoma is usually reported. Chest CT scan showed a lobulated 29-mm mass in the right upper lung and multiple hypervascular liver nodules. FDG PET/CT showed increased FDG uptake in the right upper lung nodule (SUVmax, 4.1). However, the hepatic radiouptake showed only background activity. The liver nodules were stable at the 1-year follow-up period and were suggestive of hemangiomas.
我们报告 1 例肺肉瘤样癌。患者为 31 岁男性，有传染性单核细胞增多症病史，检查发现右肺肿物。其年龄低于肺肉瘤样癌通常的发病年龄。胸部 CT 扫描显示右肺上叶有分叶状 29mm 肿块和多个富血管性肝结节。FDG PET/CT 显示右肺上叶结节 FDG 摄取增加（SUVmax，4.1）。然而，肝脏放射性摄取仅表现为背景活性。肝结节在 1 年随访期间保持稳定，提示为血管瘤。
