Pericardial cysts frequently are recognized when they present in a cardiophrenic angle, but may not be suspected when they occur elsewhere in the chest. To highlight the unusual presentations of pericardial cysts, we present two patients with cysts in the upper mediastinum and review the reported experience with similar lesions. Our patients' cysts are particularly instructive because one cyst enlarged over 23 months and because the other did not appear cystic on a computerized tomographic scan. Because percutaneous aspiration may be an attractive alternative to surgical resection when a pericardial cyst is suspected, clinicians should include pericardial cyst in the differential diagnosis of upper mediastinal masses.
心包囊肿常在心膈角处出现时被发现，但当它们出现在胸部其他部位时可能不会被怀疑。为了突出心包囊肿的不寻常表现，我们介绍了两名上纵隔囊肿患者，并回顾了有关类似病变的报道经验。我们患者的囊肿特别具有指导意义，因为一个囊肿在23个月内增大，并且另一个在计算机断层扫描上看起来不像囊肿。由于当怀疑有心包囊肿时，经皮抽吸可能是手术切除的一种有吸引力的替代方法，临床医生应将心包囊肿纳入上纵隔肿块的鉴别诊断中。
