摘要 目的分析胸腺瘤多层螺旋CT(MSCT)诊断特点,了解其最新病理学分型之间的相关性,指导临床治疗方法选择。方法回顾性分析60例经手术及穿刺病理证实胸腺瘤、胸腺癌患者的MSCT影像学特点,并与相应病理学分型进行比对研究。结果 60例患者中显示原发于前纵隔,肿块最大径5 cm,肿块边缘光滑,密度均匀,与纵隔间脂肪间隙存在并呈中等均匀强化的胸腺瘤多分布在A型中;而肿块最大径10 cm,边缘欠光滑,呈分叶状及不规则状,肿块内有坏死、囊变及钙化,周围组织侵犯和远处转移并呈显著强化者多分布在B2~B3型胸腺瘤和胸腺癌。结论 MSCT对不同类型胸腺瘤及胸腺癌的诊断尽管其存在重叠,但肿瘤较小(通常认为〈5 cm)、边缘光滑、密度均匀、均匀强化多分布于A型胸腺瘤,肿块较大、边缘欠光滑、密度不均匀、内见坏死、钙化、脂肪间隙模糊、侵及血管多为B3型胸腺瘤及胸腺癌,其诊断与组织病理类型息息相关,对临床治疗具有指导意义。
