pyogenic organisms may also be introduced to the liver by penetrating injuries or by direct continuous extension
in amoebic abscesse, the vegetative form of the organism moves from the gut to th small portal vessels and into the hepatic tissue whrere it becomes activated

the leukocytes also migrate into the infected area and form an abscess cavity filled with a liquid that contains living and dead leucocytes,liquefied liver cells and bacteria
amoebic liver abscess are large and singular and are usually secondary to infections in the biliary system,portal venous system,hepatic arterial or lympthatic systems
if the liver abscesses are not identified,they continue to grow in size and can perforate the pleural cavity,the peritoneal cavity, or the pericardial cavity
