Pericardial cysts (PCs) are uncommon benign congenital anomalies residing in the middle mediastinum. The location of PCs is diverse with 70% of cases in the right cardiophrenic angle, 22% in the left cardiophrenic angle, and 8% in the posterior (as in our case) or superior anterior part of the mediastinum. In 2019, a 54-year-old woman was referred to the emergency department of Imam Khomeini Hospital Complex (Tehran, Iran) suffering from progressive shortness of breath. The chest computed tomography scan showed an unusual giant cystic lesion occupying >50% of the right hemithorax. The cystic lesion was primarily located in the posterior mediastinum. The patient underwent video-assisted thoracoscopic surgery (VATS), and the cyst was completely resected from the mediastinum. During past decades, several cases of PCs have been reported in different age and sex groups. Here, we present a case of a giant pericardial cyst (PC) located in the posterior mediastinum. The cyst was successfully resected using VATS. Only one other study has reported a PC in the posterior mediastinum.
心包囊肿（PCs）是一种罕见的良性先天性异常，位于中纵隔。PC 的位置多样，70%位于右心膈角，22%位于左心膈角，8%位于后纵隔（如本例）或前纵隔上部。2019 年，一名 54 岁女性因进行性呼吸困难到伊朗德黑兰伊玛目霍梅尼医院综合大楼（Imam Khomeini Hospital Complex）的急诊科就诊。胸部计算机断层扫描显示一个异常的巨大囊性病变，占据了右胸腔的>50%。该囊性病变主要位于后纵隔。患者接受了电视辅助胸腔镜手术（VATS），并从纵隔完全切除了该囊肿。在过去几十年中，不同年龄和性别组的多个心包囊肿病例已被报道。在这里，我们报告了一例位于后纵隔的巨大心包囊肿（PC）。该囊肿通过 VATS 成功切除。只有另一项研究报告了一例后纵隔心包囊肿。
