Pleuropericardic cysts represent 5 to 7 per cent of tumours of the mediastinum. Their origin is a defect in development of pericardic coelomic cavities. They are located in the right and cardio-phrenic corner in 70 per cent of cases. They are generally asymptomatic. They are best treated by a thin needle puncture under scanography. Surgery is needed only when the cyst wall is thick. We have treated surgically 2 cases of large cysts, because of their sizes (10 cm and 13 cm of diametres respectively), and, mostly, because of their calcification. Symptomatology was dominated by respiratory signs, such as dyspnea. In one case, there were manifestations of inferior vena cava compression. Diagnosis was done by roentgenography of the thorax. The surgical procedure, using right thoracotomy, revealed a calcified cyst in both cases, with a tough wall, which was resected. In one case, the removal of adhesion to the inferior vena cava injured this vessel which was sutured after partial clamping. Hemorrhage was severe and 2.51 blood transfusion was necessary. The post operative course was uneventful. Clinical signs of compression disappeared in both cases.
胸膜心包囊肿占纵隔肿瘤的5%至7%。其起源是心包体腔发育缺陷。70%的病例位于右侧心膈角。它们通常无症状。最好在超声扫描引导下进行细针穿刺治疗。仅当囊肿壁增厚时才需要手术。我们手术治疗了2例大囊肿，主要是因为其大小（直径分别为10厘米和13厘米），且大多是因为其钙化。症状以呼吸症状为主，如呼吸困难。1例有下腔静脉受压表现。通过胸部X线检查进行诊断。采用右胸切开术的手术过程显示，两例均为钙化囊肿，囊壁坚韧，予以切除。1例中，因与下腔静脉粘连的分离损伤了该血管，在部分钳夹后进行了缝合。出血严重，需要输注2.5升血液。术后过程顺利。两例压迫的临床症状均消失。
