為了進一步以電腦斷層攝影作化膿性及阿米巴性肝膿瘍之鑑別診斷，我們將四十一位經證實之肝膿瘍患者的電腦斷層影像作了回溯性之研究分析。其結果顯示如后：(1)化膿性肝膿瘍傾向於產生多發性病灶且易合併有膽道疾病、腹水及肋膜積水；(2)阿米巴性肝膿瘍傾向於單一性或單一病灶合併多發性子膿瘍，並併有較高的尾葉侵犯發生率，(3)病灶周邊水腫僅見於阿米巴性肝膿瘍；(4)產氣病灶僅發生於化膿性肝膿瘍。 基於這些表徵，所以我們認為，電腦斷層攝影可以提供一簡易而又正確的方法，以區別化膿性及阿米巴性肝膿瘍。

For further differentiation of the pyogenic and amebic liver abscess with computed tomography (CT), forty-one proven hepatic abscesses examined by CT scanning were studied retrospectively. The following results were obtained : 1) pyogenic abscess were prone to develop multiple lesions and were usually associated with biliary disorders pleural effusion and ascites. 2) amebic abscess tended to develop a single lesion or a single lesion with daughter lesions and tended to involve the caudate lobe. 3) perifocal edema and hyperemia (double wall sign) was seen only in the amebic abscess. 4) gas within the abscess was seen only in the pyogenic group. These fingings, we think, will make CT differentiation of the amebic abscess from the pyogenic liver abscess easier and more accuate.
