摘　　要：目的提高纵隔囊肿的诊断与鉴别诊断水平。方法收集经手术病理证实的纵隔囊肿36例,分析其CT表现。结果所有病例CT表现均为边缘清晰、囊壁菲薄、内为不强化的水样密度肿块。其中神经肠源性囊肿1例、支气管囊肿12例、食管囊肿2例、心包囊肿5例、皮样囊肿7例、淋巴管囊肿4例、胸腺囊肿4例、非特异性囊肿1例。结论根据CT平扫和增强扫描上特征性表现,可较正确地作出纵隔囊肿的诊断,并与其它囊性病变鉴别。Objective To improve the diagnosis and differential diagnosis of mediastinal cysts. Methods 36 patients with mediastinal cyst proved by surgery and pathology were collected , and CT findings were analyzed retrospectively. Results In all 36 cases,CT defined the masses with clear margin , thin wall and fluid - like density content which had no enhancement after intravenous contrast administration. There were neurenteric cyst（ n = 1 ） , bronchial cyst（n = 12） , esophageal cyst（n =2 ） , pericardial cyst（n =5 ） , dermoid cyst（ n = 7） , lymphangioma （ n = 4 ） , thymic cyst （ n = 4 ） and non - special cyst （ n = 1 ） . Conclusion The diagnosis of mediastinal cyst and differential diagnosis from other cystic lesions can be made according to the characteristics on plain and post -contrast CT scans.
