Abstract:
Although many papers concerning the ultrasonographic findings of liver abscess have been appeared, there is afew literatures for the analysis of its echognic patterns. Twenty-nine cases of surgically proven liver abscesswere studied by ultrasonography in our hospital during recent 3 years. The results were as follows: 1.Ultrasonography permitted correct diagnosis in 26 of 29 patients with sensitivity 90%. 2. All the 7 cases ofamebic abscess were single lesions and 6 cases of them were distributed in the right lobe of liver, while pyogenicabscesses showed single or multiple lesions. It was very difficult to distinguish pyogenic abscess from amebicabscess in cases of single lesion. 3. It was impossible to differentiate pyogenic abscess from amebic abscess bythe echopattern of abscess wall and internal echogenicity. 4. The wall of obscess was ill-defined in the majority,and internal echogenecity of abscess was variable although weak internal echogenecity was more comon. 5. Theechopattern of abscess was gradually converted to echolucent or hypoechoic area with weak internal echoes infollowing up study. 6. Clinical findings and ultrasonic findings should be carefully analysed to secure correctdiagnosis of there is any possibility of co-existing necrotizing metastatic lesion.
