摘要
目的通过分析原发纵隔卵黄囊瘤的CT影像学表现,提高对本病的认识,减少误诊。方法回顾性分析本院经穿刺活检/手术病理证实的5例原发性纵隔卵黄囊瘤的CT表现。结果5例患者男4例、女1例,年龄3~35岁,平均年龄(22.2±12.1)岁,肿瘤大多形态欠规则,体积较大,病变与周围分界不清,并常压迫临近血管和器官,CT平扫一般呈等或低密度,增强扫描实性部分一般呈渐进性强化,病灶内可见分隔,呈中度至明显强化。病变早期可包绕或侵犯血管及心包;5例患者AFP血清水平指标结果均有不同程度增高。结论卵黄囊瘤CT表现具有一定特征性,结合患者年龄、性别及血清AFP水平等临床资料,CT平扫及增强检查有助于作出诊断,为患者和临床早期治疗提供帮助,减少误诊。
Objective By analyzing the CT findings of primary mediastinal yolk sac tumor,improve the understanding of the disease and reduce misdiagnosis.Methods The CT findings of 5 cases of primary mediastinal yolk sac tumor confirmed by biopsy were retrospectively analyzed.Results The 5 patients were 4 males and 1 female,aged 3 to 35 years old,with an average age of(22.2±12.1)years old.Most of the tumors were irregular in shape,large in size,unclear boundary between the lesion and the surroundings,and often compressed adjacent vessels and organs,CT plain scan is generally equal or low density,and the solid part of the enhanced scan generally shows progressive enhancement,with visible separation in the lesion,showing moderate to obvious enhancement.In the early stage of the disease,blood vessels and pericardium can be surrounded or invaded;the results of AFP serum levels in 5 patients all increased to varying degrees.Conclusion The CT manifestations of yolk sac tumor have certain characteristics.Combined with clinical data such as the patient’s age,gender and serum AFP level,CT plain scan and enhanced examination can help make the diagnosis,provide help for the patient and early clinical treatment,and reduce the rate of misdiagnosis.
