目的研究不典型肝脓肿的CT表现。方法回顾性分析13例不典型肝脓肿的CT表现及临床资料。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,CT平扫多表现为低密度肿块,增强扫描可见:①肿块缩小征;②“蜂窝征”;③“花瓣征”;④周围充血征;⑤延时强化征。结论不典型肝脓肿的CT平扫无特征性,增强扫描尤其是动态增强扫描和延时扫描有一定特征性,多征象综合分析并结合临床,多能作出正确诊断,积极抗炎治疗观察对鉴别诊断有临床价值。
Objective To study the CT findings of atypical liver abscess. Methods The CT findings and clinical data of 13 cases of atypical liver abscess were retrospectively analyzed. Results atypical liver abscess more common in the abscess of liver abscess or abscess formation of early stage, CT scan showed low-density mass, enhancement scan shows: ① shrinkage sign; ② “honeycomb sign”; ③ “petal Sign ”; ④ around the congestion sign; ⑤ delay enhanced sign. Conclusions CT scan of atypical liver abscess is characteristic of CT scan. Enhanced scan, especially dynamic contrast-enhanced scan and delayed scan, have some characteristics. Comprehensive analysis of multiple signs combined with clinical and multi-diagnosis can make correct diagnosis. Active anti- Diagnosis has clinical value.
