纤维板层型肝癌CT/MRI征象分析

目的:通过分析纤维板层型肝癌的CT/MRI影像学表现,旨在提高对本病的认识,减少误诊率。方法:通过RIS/PACS系统获取病理诊断为纤维板层型肝癌的患者7例,对CT/MRI影像学表现进行描述,并探讨其特异性征象。结果:纤维板层型肝癌影像学表现具有特异性,可以作为诊断与鉴别诊断的依据。CT/MRI表现:一般直径>10cm的单体肿瘤,边界清晰。无肝硬化背景。肿瘤实质成分动脉期混杂强化为主、门静脉期及延迟期强化趋于均匀。肿瘤内部见星状低密度影,增强可能延迟强化。结论:CT/MRI表现具有一定特异性,可以进行诊断与鉴别诊断。 

CT/MRI Sign Analysis of Fibrolamellar Hepatocellular Carcinoma

Objective: To analysis the CT and MRI findings of fibrolamellar hepatocellular carcinoma in order to improve differential diagnosis. Methods: This study obtaind to 7 cases of fibrolamellar hepatocellular carcinoma from RIS/PACS system and database for analysis and evaluation. The specificity signs was to describe. Results: Fibrolamellar hepatocellular carcinoma has more specific imaging findings, can be used as the basis for diagnosis and differential diagnosis. CT/MRI imaging findings: the lesion show single mass about diameter>10cm,with sharpness of border and complicating no hepatic cirrhosis. The mass was ennoblement promiscuity in arterial phase, ennoblement uniformity in venous phase and delay phase. Central stellate scar maybe delayed reinforcement. Conclusion: CT/MRI imaging show some specificity signs lead to be diagnosis and differential diagnosis for fibrolamellar hepatocellular carcinoma.
