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 ...
If the parasite reaches the bloodstream it can spread through the body, most frequently ending up in the liver where it can cause amoebic liver abscesses. [2] Liver abscesses can occur without previous diarrhea. [2] Diagnosis is made by stool examination using microscopy, but it can be difficult to distinguish E. hystolitica from other harmless ...
In the liver a similar pathological sequence ensues, leading to amebic liver abscesses. The trophozoites can also end up in other organs, sometimes via the bloodstream, sometimes via liver abscess rupture or fistulas. Similarly, when the trophozoites travel to the brain, they can cause amoebic brain abscesses. [26]
For amebic liver abscess: Metronidazole 400 mg three times a day for 10 days; Tinidazole 2g once a day for 6 days is an alternative to metronidazole; Diloxanide furoate 500 mg three times a day for 10 days (or one of the other lumenal amebicides above) must always be given afterwards
In treatment of amoebic liver abscess, chloroquine may be used instead of or in addition to other medications in the event of failure of improvement with metronidazole or another nitroimidazole within five days or intolerance to metronidazole or a nitroimidazole.
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.

With correct treatment, most cases of amoebic and bacterial dysentery subside within 10 days, and most individuals achieve a full recovery within two to four weeks after beginning proper treatment. If the disease is left untreated, the prognosis varies with the immune status of the individual patient and the severity of disease.
