*Uncommon overall, usually right liver lobe
*More abscesses -> more severe disease
*Camping history
*Endemic of Midwest
*Two types: pyogenic and amebic
**Pyogenic
***More common of the two
***Associated with biliary tract obstruction (most common), cholangitis, diverticulitis, pancreatic abscess, appendicitis and inflammatory bowel disease.
***Possible arterial hematogenous seeding: sepsis, direct trauma or instrumentation
**Amebic
