摘　　要：目的探讨原发性心包恶性间皮瘤的CT表现及特征。资料与方法回顾性分析经病理证实的2例心包恶性间皮瘤的CT表现,并与临床病理作探讨分析。2例均行CT平扫加增强扫描,并行多平面重组(MPR)观察。结果左心缘旁巨大囊性占位1例,平扫CT值21～24HU,增强扫描囊内不强化,囊壁实质成分轻度强化,CT值47HU,心脏局部有受压深度凹陷征象,肿块部分深入升主动脉与上腔静脉后缘。心包大量积液1例,平扫前中纵隔肿块基本与心包积液呈等密度,CT值32～36HU,增强扫描肿块呈轻度强化,CT值45～51HU,肿块与前纵隔血管分界不清,并向后蔓延至左上肺静脉前缘。结论心包恶性间皮瘤CT表现复杂但有一定特征性,CT增强扫描能够确定肿块大小和范围,为临床诊断提供可靠依据。Objective To explore the CT features of primary malignant pericardial mesothelioma. Materials and Methods The CT imaging data of 2 patients with pericardial malignant mesothelioma confirmed by pathological results were analyzed retrospectively. Two patients received enhanced CT examination,and MPR reconstruction was used. Resu-lts One patient had giant cystic mass close to left cardia border,CT value of the lesion was 21-24HU and no enhancement was found in the central area.The wall of the lesion had slightly enhancement and the CT value was 47HU,focal area of the heart was compressed and the lesion inserted between ascending aorta and superior vena cava. Another patient had large amount of preicardiall effusion,CT value of the lesion was 32-36HU similar to effusion,and had mild enhancement,the CT value was 45-51HU. There was no clear boundary between the lesion and vessels of anterior mediastinum,and the lesion spreaded to the anterior boundary of left superior pulmonary vein. Conclusion The CT features of pericardial malignant mesothelioma are complex,enhanced CT scan can clearly depict the border and size of the mass and provide some evidence for clinical diagnosis.
