A 65-year-old woman with history of sarcoidosis, hypertension, and peripheral vascular disease presented with lower extremity claudication and low left ventricular ejection fraction of 45% on echocardiogram. Further FDG PET/CT revealed hypermetabolic bilateral chest lymphadenopathy and pulmonary nodules in a butterfly-shaped distribution pattern, which was typically seen in patients with sarcoidosis. In addition, abnormal increased radiotracer uptake was present in pericardium, and along the walls of inferior vena cava, aorta, and pulmonary artery, which correlated with delayed enhancement on further cardiac MRI. These findings were suggestive of sarcoid-related pericarditis and great vessel vasculitis.
一位 65 岁女性，有结节病、高血压和外周血管疾病病史，表现为下肢跛行，超声心动图显示左心室射血分数为 45%。进一步的 FDG PET/CT 显示双侧胸部淋巴结肿大和蝶形分布的肺部结节，这在结节病患者中很常见。此外，心包和下腔静脉、主动脉和肺动脉壁上还存在异常放射性示踪剂摄取增加，与进一步的心脏 MRI 延迟增强相对应。这些发现提示结节病相关的心包炎和大血管血管炎。
