Pulmonary artery involvement can occur in about half of the patients suffering Takayasu arteritis. Increased FDG activity in the aorta and its main branches in patients with Takayasu arteritis on PET/CT had been well-reported. However, the FDG PET/CT appearance of pulmonary artery involvement in Takayasu arteritis is less known. We present FDG PET/CT findings in a 37-year-old patient with known Takayasu arteritis. The images showed rim-like FDG activity in opacities in the left lung, which was later proven due to narrowed left main pulmonary artery.
肺动脉受累在约半数大动脉炎患者中均可发生。在 PET/CT 上，大动脉炎患者的主动脉及其主要分支 FDG 活性增高已有报道。然而，大动脉炎肺动脉受累的 FDG PET/CT 表现知之甚少。我们报道 1 例已知大动脉炎的 37 岁患者的 FDG PET/CT 表现。图像显示左肺不张处呈边缘样 FDG 活性摄取，后来证实是由于左肺动脉主干狭窄。
