Pericardial cysts (PCs) are very rare, often congenital, mediastinal masses. Usually, they are located in the right cardiophrenic angle and only in 8% of cases in the anterior or posterior mediastinum. Computed tomography and/or magnetic resonance imaging are accurate tools for the diagnosis and characterization of mediastinal masses. However, echocardiography is, in many cases, a good screening technique. If asymptomatic, they do not require surgical excision. The authors describe a case of posterior mediastinum PC; in these cases, echocardiography cannot see the mass and three-dimensional imaging techniques are required. The clinical management of this case is discussed.
心包囊肿（PCs）是非常罕见的，通常为先天性纵隔肿物。它们通常位于右心膈角，仅8%的病例位于前纵隔或后纵隔。计算机断层扫描和/或磁共振成像对于纵隔肿物的诊断和特征描述是准确的工具。然而，在许多情况下，超声心动图是一种很好的筛查技术。如果无症状，不需要手术切除。作者描述了一例后纵隔心包囊肿病例；在这些病例中，超声心动图无法看到肿物，需要三维成像技术。本文讨论了该病例的临床处理。
