不典型肝脓肿的CT动态增强表现及相关病理
Journal of Medical Imaging（2011）
Abstract
目的:探讨不典型肝脓肿的CT动态增强表现及其病理基础,提高对肝脓肿的诊断水平.方法:回顾分析经临床证实的12例不典型肝脓肿的临床资料及CT表现.结果:不典型肝脓肿的CT表现具有多样性:CT平扫病灶呈均匀或不均匀低密度区,形态呈类圆形,边缘模糊或较清楚.增强扫描动脉期病灶呈轻度强化,门静脉期病灶呈小环状、蜂窝状、花瓣状、网格状、簇状表现,夹杂不明显强化的低密度区,延时期病灶仍有强化表现.其多样的CT征象与肝脓肿所处时期密切相关.结论:螺旋CT动态多期增强扫描有助于不典型肝脓肿的诊断,对判断脓肿的病理过程和指导临床工作具有重要意义.
