A liver abscess is a collection of pus in the liver caused by bacteria, fungi, or parasites. It may occur as a single lesion or as multiple lesions of different sizes. It is commonly caused by an infection with bacteria (germs) or ameba (parasite that causes Diarrhea). A bacterial liver abscess often happens after an abdominal (stomach) infection. This may include infections of the bile ducts caused by Gallstone, infection in the intestines, or Appendicitis. Pain on the right upper part of your abdomen, fever, and night sweats are common signs and symptoms. You may also have loss of appetite, nausea (upset stomach), vomiting (throwing up), or unplanned weight loss. Sometimes, cough, trouble breathing, or yellowing of the skin and whites of the eyes, may be present.

A liver abscess may be diagnosed by blood or imaging tests that take pictures of your abdomen. These may include x-rays, liver scan, ultrasound, computerized tomography (CT) scan, and a magnetic resonance imaging (MRI). Treatment will depend on the cause, size, and location of your liver abscess. It will also depend on whether you have a single or multiple abscesses. Medicines may be given to kill the infection and ease your symptoms. Caregivers may drain the abscess or do surgery to help remove the pus in your liver. With treatment and care, your abscess may be cured and serious problems may be prevented.
