摘要
目的探讨胆管错构瘤的CT表现,旨在提高对本病的认识。方法回顾性分析经穿刺活检病理证实的5例胆管错构瘤患者的CT表现,并结合文献,对本病的病理、临床以及CT表现特点进行讨论。结果 CT平扫显示病灶呈多发低密度,大小不等,形态各异,边缘部分清楚,部分不清,增强扫描后无强化。其中1例行MRI平扫,病灶呈长T_1、长T_2信号MRCP显示肝内多发类囊状高信号病变,与胆管树不相通,肝内胆管树分支未见异常。结论正确认识胆管错构瘤的CT表现特点,对本病的诊断以及鉴别诊断有较大的帮助,最终确诊有赖于采取活体组织进行病理学检查。
Objective To assess CT features of biliary hamartoma. Methods The CT of 5 patients with histologically confirmed biliary hamartomas was retrospectively analyzed. Results The lesions were manifested as well-defined low densities of varying size and shape on unenhanced and contrast-enhanced CT. MRI showed low T1 and high T2 signals without any connection with the bile ducts on MRCP. Conclusion Understanding the CT features of this disease is helpful for diagnosis.
