NEJM:“满天星”状的胆道错构瘤-病例报道

2020-04-16 MedSci原创 MedSci原创

磁共振成像与胆管造影显示肝脏有多个细小T2加权高信号囊性结节,这些结节与胆管不相通,呈现出一个“满天星”的外观(如图B所示)。这些发现与胆道错构瘤的特征一致,伴有良性肝内胆道畸形的导管。

患者为一名45岁的妇女,偶然的一次影像学检查时发现多处肝脏病变后到门诊就诊。

她无相关症状,体格检查未见异常。实验室检查无肝功能障碍,丙氨酸氨基转移酶、碱性磷酸酶、胆红素水平正常,国际标准化比值也正常。腹部增强CT发现整个肝脏有多个细小低密度非增强结节(如图A所示)。

磁共振成像与胆管造影显示肝脏有多个细小T2加权高信号囊性结节,这些结节与胆管不相通,呈现出一个“满天星”的外观(如图B所示)。这些发现与胆道错构瘤的特征一致,伴有良性肝内胆道畸形的导管。

该患者没有接受特殊的治疗,在2年后的随访中,影像学表现没有改变。
