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.
动脉瘤的特征是血管壁因薄弱而出现局灶性扩张。血管壁两层受累被归类为假性动脉瘤，而三层均受累则称为真性动脉瘤。肿瘤性病变累及动脉瘤较为罕见，但少数已报道的病例与肺动脉假性动脉瘤相关，而非真性肺动脉瘤（PAA）。据我们所知，我们所报道的一例肺转移性肉瘤患者发生左肺真性PAA的病例显示了一种此前未被报道过的关联。
