The two most common manifestations of E histolytica include colitis (bloody stool with mucus, abdominal pain, and/or diarrhea), and discovery of a liver abscess on imaging. [2] Liver abscesses commonly present as right upper quadrant abdominal pain and fever, with worsening features associated with abscess rupture. [2] Magnetic resonance ...
A large pyogenic liver abscess presumed to be the result of appendicitis. There are several major forms of liver abscess, classified by cause: [3] Pyogenic liver abscess, which is most often polymicrobial, accounts for 80% of hepatic abscess cases in the United States. Amoebic liver abscess due to Entamoeba histolytica accounts for 10% of cases ...
Pulmonary amoebiasis can occur from liver lesions by spread through the blood or by perforation of pleural cavity and lung. It can cause lung abscess, pulmono pleural fistula, empyema lung and broncho pleural fistula. It can also reach the brain through blood vessels and cause amoebic brain abscess and amoebic meningoencephalitis.
Symptoms of this infection include diarrhea with blood and mucus, and can alternate between constipation and remission, abdominal pain, and fever. Symptoms can progress to ameboma, fulminant colitis, toxic megacolon, colonic ulcers, leading to perforation, and abscesses in vital organs like liver, lung, and brain.
E. histolytica, as its name suggests (histo–lytic = tissue destroying), is pathogenic; infection can be asymptomatic, or it can lead to amoebic dysentery or amoebic liver abscess. [ 6 ] [ 7 ] Symptoms can include fulminating dysentery, bloody diarrhea, weight loss, fatigue, abdominal pain, and amoeboma .
The amoebae inside the cyst are protected from the stomach's digestive acid. From the stomach, the cyst travels to the intestines, where it breaks open and releases the amoebae, causing the infection. The amoebae can burrow into the walls of the intestines and cause small abscesses and ulcers to form. The cycle then begins again. [citation needed]

To differentiate pyogenic liver abscess from amoebic liver abscess, several features such as subjects with age more than 50 years with lungs involvement, multiple liver abscesses, with amoebic serologic titres less than 1:256 can help to pin down the diagnosis of pyogenic liver abscess.
