We report the F-18 FDG PET/CT findings in a 59-year-old man with a rare hepatic tumor of malignant epithelioid hemangioendothelioma, who was treated with radiotherapy (RT). This patient had multifocal discrete hepatic tumors, and PET/CT images showed intense FDG uptake in these nodules, regardless of poor enhancement on contrast-enhanced computed tomography. Seven months after RT to the 2 relatively large nodules, the intense FDG uptake disappeared in these nodules, while the remaining untreated nodule showed persistently intense uptake. RT is one of the options for treatment of hepatic epithelioid hemangioendothelioma. F-18 FDG PET/computed tomography appears to be useful for monitoring the effect of RT in this neoplasm.
我们报告了一名59岁男性恶性上皮样血管内皮细胞瘤罕见肝肿瘤患者的F-18 FDG PET/CT检查结果，该患者接受了放射治疗（RT）。此患者有多发散在性肝肿瘤，PET/CT图像显示这些结节中有强烈的FDG摄取，尽管在对比增强计算机断层扫描上强化不佳。对2个相对较大的结节进行放射治疗7个月后，这些结节中强烈的FDG摄取消失，而其余未治疗的结节仍显示持续强烈摄取。放射治疗是肝上皮样血管内皮细胞瘤的治疗选择之一。F-18 FDG PET/计算机断层扫描似乎有助于监测该肿瘤放射治疗的效果。
