<unk>  is a pus-filled cavity inside or attached to the liver.  Common causes are an abdominal infection such as appendicitis or diverticulitis.  With treatment the prognosis of<unk>  is poor with a mortality rate is 10-30%.. 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 are seen in the majority of patients, but it has a low specificity. E. coli is the most common causative organism, followed by Klebsiella, Streptococcus, and Bacteroides species. Rare cause is bowel perforation following foreign body ingestion. Therapy for solitary<unk>  from causes other than bowel perforation is intravenous antibiotics and percutaneous ultrasonography or CT-guided drainage. Therapy for<unk>  caused by bowel perforation or foreign body is open surgical drainage. Amoebic<unk>  occurs in 94% of cases of amebiasis.<unk>  can be caused rarely as complication of percutaneous radiofrequency ablation for hepatic tumors.
