A liver abscess is a localized, pus-filled cavity within the hepatic parenchyma characterized by tissue destruction, liquefactive necrosis, and surrounding inflammation Etiologies are predominantly pyogenic—frequently polymicrobial with enteric pathogens such as *Escherichia coli* and *Klebsiella pneumoniae*—or amebic, caused by *Entamoeba histolytica* Clinically, affected patients characteristically present with systemic manifestations including fever, chills, leukocytosis, and right upper quad...

It primarily affects the gastrointestinal and hepatobiliary systems and arises through ascending biliary infection, hematogenous seeding via the portal or systemic circulation, direct extension from adjacent abdominal structures, or penetrating trauma Etiologies are predominantly pyogenic—frequently polymicrobial with enteric pathogens such as *Escherichia coli* and *Klebsiella pneumoniae*—or amebic, caused by *Entamoeba histolytica* Clinically, affected patients characteristically present with ...

It primarily affects the gastrointestinal and hepatobiliary systems and arises through ascending biliary infection, hematogenous seeding via the portal or systemic circulation, direct extension from adjacent abdominal structures, or penetrating trauma Clinically, affected patients characteristically present with systemic manifestations including fever, chills, leukocytosis, and right upper quadrant abdominal pain, which carry a significant risk of sepsis or rupture if left untreated
