We herein report an unreported case of pyogenic granuloma that originated in the pulmonary artery. A 38-year-old man was urgently hospitalized with dyspnea and back pain. He had been on hemodialysis for 2 years due to chronic renal failure. We performed contrast-enhanced computed tomography and detected a mass occluding the left main pulmonary artery. The maximum standardized uptake value (SUV) of F-fluorodeoxy glucose (FDG) in the mass was 4.1. We made a tentative diagnosis of pulmonary artery tumor, and planned an operation. We performed median sternotomy and left anterolateral thoracotomy. As the tumor had not reached the bottom of the left pulmonary artery, we first performed left upper lobectomy. We then performed resection of the pulmonary artery tumor under cardiopulmonary bypass and reconstructed the pulmonary artery with self-pericardium. The pathological diagnosis was pyogenic granuloma. To our knowledge, pyogenic granuloma originating in the pulmonary artery has never been reported before.
我们在此报告一例起源于肺动脉的化脓性肉芽肿病例，此前未见报道。一名38岁男性因呼吸困难和背痛紧急入院。他因慢性肾衰竭已接受血液透析2年。我们进行了增强计算机断层扫描，发现一个肿块阻塞了左主肺动脉。肿块中F-氟脱氧葡萄糖（FDG）的最大标准化摄取值（SUV）为4.1。我们初步诊断为肺动脉肿瘤，并计划进行手术。我们实施了正中胸骨切开术和左前外侧开胸术。由于肿瘤尚未到达左肺动脉底部，我们首先进行了左上肺叶切除术。然后在体外循环下切除肺动脉肿瘤，并用自体心包重建肺动脉。病理诊断为化脓性肉芽肿。据我们所知，起源于肺动脉的化脓性肉芽肿此前从未有过报道。
