摘　　要：目的:探讨纵隔血管瘤及淋巴管瘤的MSCT表现,提高对此类疾病的影像诊断水平。方法:搜集15例经病理证实的纵隔血管瘤及淋巴管瘤,回顾性分析其CT表现。结果:血管瘤4例,表现为纵隔软组织肿块,边界清晰,密度可均匀或不均匀,静脉石为其特征性表现,增强扫描呈渐进性强化或延迟强化。淋巴管瘤7例,表现为纵隔均匀低密度灶,可包绕纵隔结构或沿纵隔大血管间隙弥漫生长,增强扫描呈囊性不强化或仅囊壁及分隔轻度强化。血管淋巴管瘤4例,表现变异较大,以血管瘤为主者表现为软组织肿块,密度多不均匀,增强扫描实性成分与静脉强化相似;以淋巴管瘤为主者表现为低密度灶内可见静脉成分(静脉石或小血管影)。结论:CT对纵隔血管瘤及淋巴管瘤的诊断具有重要价值,在指导临床治疗中发挥重要作用。Objective:To investigate the MSCT manifestations of mediastinal hemangioma and lymphangioma,and to improve the imaging diagnosis of such diseases.Methods:Fifteen cases of mediastinal hemangioma and lymphangioma confirmed by pathology were collected and their CT manifestations were analyzed retrospectively.Results:A total of 4 cases of hemangioma were manifested as well-defined mediastinal soft tissue masses with homogeneous or heterogeneous density,and phlebolith was its specific sign.In addition,hemangioma showed progressive enhancement or delayed enhancement during enhanced CT scan.The lymphangioma(n=7)presented homogeneous low-density mediastinal masses,which could surround the mediastinal structure or diffusely grow along the mediastinal great vascular space,and showed cystic non-enhancement or only slightly enhanced cyst wall and septation after contrast enhancement.There were 4 cases of hemolymphangioma with large variation in manifestations.The masses with lymphangioma dominated showed soft tissue with inhomogeneous density,and the solid components of enhanced scan were similar to venous enhancement,and the masses with lymphangioma dominated manifested as venous components(phlebolith or small vascular)in low-density lesions.Conclusion:CT has important value in the diagnosis of mediastinal hemangioma and lymphangioma,and plays an important role in guiding clinical treatment.
