Abstract
|
|
|
To differentiate amebic and pyogenic liver abscesses, sonography(US) and CT findings of 21 amebic and 22 pyogenic liver abscesses were reviewed retrospectively. US was performed in all cases and CT in 15 cases of each group.
Eleven cases of amebic abscesses had well defined margin which was observed in 10 cases of pyogenic abscessed. Amebic abscesses showed hyperechoic wall in 7 cases and calcification in 4 cases. Ten cases of pyogenic abscesses had mearby
intrahepatic
duct
dilatation which was observed in 2 cases of amebic abscesses. Pneumobilia was seen in 6 cases of pyogenic abscesses.
US findings of clear margin and hyperechoic wall, and CT findings of intrahepatic duct dilatation, pneumobilia, and calcification were helpful in differentation of amebic pyogenic liver abscesses.
