Abstract：
Aneurysms are characterized by focal dilation of the blood vessel wall due to weakening. The involvement of two layers of the vessel wall is classified as a pseudoaneurysm while the involvement of all three layers is called a true aneurysm. Involvement of neoplastic lesions is rare, but the few reported cases have been associated with pulmonary artery pseudoaneurysms as opposed to true pulmonary artery aneurysms (PAAs). Our case of a true left PAA of a patient with metastatic sarcoma of the lung shows an association that has previously not been reported to the best of our knowledge.
摘要：
动脉瘤的特征在于由于弱化导致的血管壁的局灶性扩张。两层血管壁的参与被分类为假性动脉瘤,而所有三层的参与被称为真正的动脉瘤。肿瘤性病变的参与是罕见的，但是少数报道的病例与肺动脉假性动脉瘤有关，而不是真正的肺动脉动脉瘤（PAAs）。我们的肺部转移性肉瘤患者的真实左PAA病例显示，据我们所知，这种关联以前从未报道过。
