Abstract

Pulmonary artery sarcoma is an uncommon neoplasm, and its clinical and radiological presentation usually simulates chronic thromboembolic disease. We present the case of a 77-year-old woman admitted with dyspnea, chest pain, and hemoptysis. A chest computed tomographic scan showed moderate right-sided pleural effusion and a saccular dilatation of the interlobar portion of the right pulmonary artery, which was filled with contrast and surrounded by an irregular soft-tissue attenuation mass, suggesting a ruptured pulmonary artery aneurysm. The patient was operated on. Intraoperatively, a pseudoaneurysm and a solid mass were identified within the oblique fissure around the interlobar artery. Therefore, a right pneumonectomy was performed. Definitive pathologic examination was consistent with pulmonary artery sarcoma. The patient had a good outcome and is free of disease 2 years after surgery.

摘要

肺动脉肉瘤是一种罕见的肿瘤，其临床和影像学表现通常类似于慢性血栓栓塞性疾病。我们报告一例77岁女性患者，因呼吸困难、胸痛和咯血入院。胸部计算机断层扫描显示右侧中度胸腔积液以及右肺动脉叶间部囊状扩张，其中充满造影剂，并被不规则软组织密度肿块包绕，提示肺动脉瘤破裂。患者接受了手术。术中，在叶间动脉周围的斜裂内发现一个假性动脉瘤和一个实性肿块。因此，实施了右肺切除术。最终病理检查结果符合肺动脉肉瘤。患者预后良好，术后2年无疾病复发。
