We report a very rare case of pulmonary artery sarcoma that presented as an isolated lung mass, which we attempted to resect via lobectomy, although this resulted in incomplete resection due to unnoticed latent proximal presentations. A 54-year-old man complained of a dry cough that had persisted for 2 months. Enhanced chest computed tomography revealed a lobular mass in his left lower lobe. Therefore, left lower lobectomy was performed as a radical surgery, and the tumor was ultimately diagnosed as pulmonary artery sarcoma. However, follow-up computed tomography at 16 months revealed proximal presentations in the pulmonary trunk and right pulmonary artery, which we retrospectively discovered were present before the surgery. This case highlights the importance of evaluating the lumen of the pulmonary artery, to accurately determine the required extent of any radical surgery, even in cases of pulmonary artery sarcoma that presents as an isolated lung mass.
我们报告了一例非常罕见的肺动脉肉瘤病例，该病例表现为孤立性肺肿块，我们试图通过肺叶切除术将其切除，但由于未注意到潜在的近端病变，导致切除不完全。一名54岁男性主诉干咳持续2个月。胸部增强计算机断层扫描显示其左下叶有一个分叶状肿块。因此，作为根治性手术进行了左下叶切除术，肿瘤最终被诊断为肺动脉肉瘤。然而，术后16个月的随访计算机断层扫描显示，肺动脉主干和右肺动脉出现近端病变，我们回顾性发现这些病变在手术前就已存在。该病例强调了评估肺动脉管腔的重要性，以便准确确定任何根治性手术所需的范围，即使是表现为孤立性肺肿块的肺动脉肉瘤病例。
