A postmyocardial infarction left ventricular pseudoaneurysm occurs when a rupture of the ventricular free wall is contained by overlying, adherent pericardium. A postinfarction aneurysm, in contrast, is caused by scar formation resulting in thinning of the myocardium. Although the usual treatment for patients with pseudoaneurysm is urgent surgical repair, the imaging characteristics of pseudoaneurysm and aneurysm, for which treatment is more conservative, are quite similar. The literature on the natural history and imaging characteristics of the two entities is reviewed, and an approach to distinguishing between the two entities is proposed.
心肌梗死后左心室假性动脉瘤是指心室游离壁破裂被覆盖其上且与之粘连的心包所包裹。相比之下，梗死性动脉瘤是由瘢痕形成导致心肌变薄所致。虽然假性动脉瘤患者的常规治疗是紧急手术修复，但假性动脉瘤和动脉瘤的影像学特征颇为相似，而动脉瘤的治疗更为保守。本文回顾了关于这两种病变的自然病史和影像学特征的文献，并提出了一种区分这两种病变的方法。
