An 81-year-old man underwent F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) to evaluate a mediastinal mass, which was discovered during the investigation for hemoptysis. The periphery of the mass abutting the aortic arch demonstrated heterogeneously increased FDG uptake, whereas most of the central portion of the mass was photopenic. The mass turned out to be an atheromatous organizing hematoma associated with contained aortic rupture.
一名81岁男性因咯血检查时发现纵隔肿块,遂行F-18氟脱氧葡萄糖(FDG)正电子发射断层扫描/计算机断层扫描(PET/CT)检查。肿块毗邻主动脉弓的周边部分FDG摄取呈不均匀增加,而肿块的大部分中央部分呈放射性缺损。结果发现该肿块是一个与主动脉夹层破裂相关的动脉粥样硬化性机化血肿。
