Pulmonary artery dissection (PAD) is a rare diagnosis that is often made postmortem in patients with pulmonary hypertension. It can be visualized by echocardiography, computed tomography, or magnetic resonance imaging. We present a patient with emphysematous chronic obstructive pulmonary disease and secondary pulmonary hypertension in whom a PAD appeared like a mediastinal mass on computed tomography. The diagnosis was made at autopsy. We think that physicians should consider the possibility of a PAD in patients with chronic pulmonary hypertension who present with dyspnea and chest pain.
肺动脉夹层（PAD）是一种罕见的诊断，在肺动脉高压患者中通常是死后诊断。它可以通过超声心动图、计算机断层扫描或磁共振成像来显示。我们报告了一例患有气肿性慢性阻塞性肺疾病和继发性肺动脉高压的患者，其 PAD 在计算机断层扫描上表现为纵隔肿块。该诊断是在尸检时做出的。我们认为，对于出现呼吸困难和胸痛的慢性肺动脉高压患者，医生应考虑 PAD 的可能性。
