目的 :探讨不典型肝脓肿的临床及 CT表现特点。方法 :回顾性分析 2 1例经临床或病理证实的不典型肝脓肿患者的临床表现和 CT图像特点。结果 :不典型肝脓肿 CT表现平扫为边缘模糊的低密度灶 ,密度不均 ,增强后动脉期 ,静脉期可见病灶边缘及其内分隔明显强化 ,平衡期及延时扫描病灶较前缩小 ,但无血管瘤的完全“充填”现象。结论 :运用螺旋 CT的动态扫描方法 ,结合不典型肝脓肿的临床表现 ,可显著提高不典型肝脓肿 CT诊断的正确率
Objective: To investigate the clinical and CT features of atypical liver abscess. Methods: Clinical features and CT features of 21 patients with clinically or pathologically confirmed atypical liver abscess were retrospectively analyzed. Results: The CT findings of atypical liver abscess were blurred low-density lesions with uneven edge. The density of the lesion was uneven after the enhancement. After the enhancement of the arterial and venous phases, the border of the lesion and the internal separation of the lesions were obviously enhanced. The balance and delayed- However, there is no complete “filling” of hemangiomas. Conclusion: The dynamic CT scan and combined with the clinical manifestations of atypical liver abscess can significantly improve the accuracy of CT diagnosis of atypical liver abscess
