Intimal sarcoma of the pulmonary artery is a rare entity, mimicking acute or chronic pulmonary thromboembolism. We describe 68 Ga-FAPI-04 and 18 F-FDG PET/CT findings in a case with intimal sarcoma of the pulmonary artery. The intrapulmonary artery tumor showed inhomogeneously increased FDG and FAPI uptake. Compared with FDG PET/CT, FAPI PET/CT more clearly delineated the tumor partially because of a very low background FAPI activity in the walls of the main pulmonary artery and right ventricle, which showed diffuse FDG uptake.
肺动脉内膜肉瘤是一种罕见的实体瘤，其表现类似于急性或慢性肺血栓栓塞症。我们描述了一例肺动脉内膜肉瘤患者的 68Ga-FAPI-04 和 18F-FDG PET/CT 表现。肺动脉内肿瘤表现为不均匀摄取 FDG 和 FAPI。与 FDG PET/CT 相比，FAPI PET/CT 更清晰地描绘了肿瘤，部分原因是主肺动脉和右心室壁的 FAPI 活性非常低，呈现弥漫性 FDG 摄取。
