目的：分析不典型肝脓肿多排螺旋CT影像表现及其病理基础，探讨其对不典型肝脓肿的诊断价值。方法回顾性分析27例不典型肝脓肿的病例资料，所有病例均行多排螺旋CT平扫及动态增强扫描。结果不典型肝脓肿多见于肝脓肿的化脓性炎症期或脓肿形成初期，肝脓肿病变发展具有个体化差异，平扫呈片状低密度病灶，或多房性低密度肿块，边界多不清晰，增强后可见相对典型征象。结论不典型肝脓肿多层螺旋CT动态增强后可显示特征性表现，大大提高了早期细菌性肝脓肿的诊断准确性。%Objective To analyze the multi-slice spiral CT findings and pathological basis of atypical hepatic abscess, and evaluate diagnostic value for atypical hepatic abscess. Methods Retrospectively analyze the clinical data of 27 cases with atypical liver abscess, all patients underwent multi-slice spiral CT scan and dynamic contrast-enhanced scan. Results Atypical liver abscess was more common in liver abscess purulent inflammation or abscess formation of early phase, and it had individual differences during disease development. Plain scan showed patchy low-density lesions, or atrial mass density, and multi-boundary was not clear, when enhanced, relatively typical signs could be seen. Conclusion Atypical hepatic abscess dynamic enhanced spiral CT can show characteristic features, greatly improving the early diagnosis of pyogenic liver abscess accuracy.
