| A liver [[abscess]] is a pus-filled mass inside or attached to the [[liver]]. Common causes are an abdominal infection such as [[appendicitis]] or [[diverticulitis]]. With treatment, the death rate is 10-30%.<ref name="MedlinePlus">{{cite web | url=http://www.nlm.nih.gov/medlineplus/ency/article/000261.htm | title='MedlinePlus Medical Encyclopedia: Pyogenic liver abscess'}}</ref>. Biliary tract disease is the most common cause but no cause identified in the majority of patients. There are nonspecific clinical findings hence a high degree of suspicion required for diagnosis. There are most often single, rather than multiple foci. Hyperbilirubinemia and elevated [[alkaline phosphatase]] in the majority of patients, but low specificity. [[E. coli]] is the most prevalent organism, followed by [[Klebsiella]], [[Streptococcus]], and [[Bacteroides]] species. Rare cause is bowel perforation following foreign body ingestion. Therapy for solitary liver abscess from causes other than bowel perforation is [[intravenous]] [[antibiotic]]s and percutaneous US- or CT-guided drainage. Therapy for liver abscess caused by bowel perforation or foreign body is open surgical drainage. Amebic liver abscess occurs in 94% of cases of [[amebiasis]]. Liver abscess is a relatively infrequent (1.7% according to Cho, D. et. al.), although possible, complication of [[percutaneous]] [[radiofrequency ablation]] of hepatic tumors.
