Abstract

IgG4-related peripulmonary arteritis is rare. A 60-year-old woman presented with fatigue for more than 2 years. Transthoracic echocardiography revealed a lesion measuring 2.1 × 1.5 cm in the pulmonary artery bifurcation. CT pulmonary angiography showed marked stenosis of the right and left pulmonary arteries. FDG PET/CT showed increased FDG uptake of the thickened walls in the bilateral pulmonary arteries with SUVmax of 5.8. The patient underwent partial resection of the pulmonary artery lesion. IgG4-related peripulmonary arteritis was confirmed by pathology.

摘要

IgG4 相关的肺血管炎罕见。一位 60 岁女性因乏力 2 年余就诊。经胸超声心动图发现肺动脉分叉处有 2.1×1.5cm 的病灶。CT 肺动脉造影显示右、左肺动脉显著狭窄。FDG PET/CT 显示双侧肺动脉壁增厚，FDG 摄取增加，SUVmax 为 5.8。患者接受了肺动脉病变的部分切除术。病理证实为 IgG4 相关的肺血管炎。
