摘　　要：目的:探讨前纵隔常见肿瘤的临床、病理及影像学特点。方法:回顾性分析经手术、穿刺活检病理证实的前纵隔肿瘤48例,并结合临床、病理资料进行对照分析。结果:胸腺瘤占50%(24例),均位于前上纵膈,11例可见囊变、坏死区或钙化,增强后呈轻度或不均匀强化。畸胎瘤占23%(11例),前上纵隔5例,前下纵隔6例,以囊实性为主,其内可见软组织、液体、脂肪及钙化成份,囊壁及实性成份呈轻中度强化。淋巴瘤17%(8例),可见多个结节样软组织融合呈团块状肿物,2例见坏死、囊变区,呈轻度强化或无强化。胸内甲状腺肿6%(3例)。心包囊肿4%(2例)。结论:依据前纵隔常见肿瘤发病部位、密度以及周围组织结构的关系,结合患者年龄伴随体征等特征,可提高前纵隔肿瘤的诊断与鉴别诊断准确率。tumors were solid mass with cystic mass,tumor necrosis areas or calcifications (n =11),mild or uneven enhancement on post -contrast CT.23% of patients were teratoma.5 located on the front supper mediastinum and 6 located on the front lower mediastinum.The tumors were mainly cystic -solid mass and soft tissue,liquid,fat and calcification ele-ments were also among them.Mild -to -moderate reinforcement on post -contrast CT.17% of patients were lympho-ma,multiple nodular soft tissue fusion conglobation block mass.2 showed tumor necrosis areas and cystic -solid mass,mild -to -moderate reinforcement on post -contrast CT.6% of patients were intra mediastinum struma,4%pericardial cyst.Conclusion:Imaging characteristics and clinical manifestations and pathological features of anterior mediastinal tumors are helpful in the diagnosis and differential diagnosis of anterior meditational tumors.
