Localized accumulation of pus in the liver; often due to amebiasis.
A pus-filled sac in the liver that may be caused by an amebic infection, a bacterial infection, or trauma. Symptoms include night sweats, fever, chills, nausea, vomiting, loss of appetite, weight loss, and abdominal pain. Diagnosis is made through blood tests, X rays, and ultrasound scanning. Depending on the underlying cause of an abscess, anti-amebic drugs such as metronidazole or antibiotics are prescribed. Treatment for a liver abscess may include draining it by needle aspiration (removal of fluid by suction), catheter drainage, or open surgical drainage.
