Which type of abscess is commonly associated with cholangitis, sepsis, and penetrating trauma to the liver?

An intrahepatic abscess is the type of abscess commonly associated with cholangitis, sepsis, and penetrating trauma to the liver.

This type of abscess typically occurs within the liver parenchyma, often as a result of infection that can spread from the biliary system, especially in cases of cholangitis where bile duct infections may lead to pus formation. The liver can become a site for abscess formation after sepsis, where systemic infections lead to localized infections within the organ. Penetrating trauma can also introduce pathogens directly into the liver, thereby causing necrosis and subsequent abscess development.

Intrahepatic abscesses are characterized by their potential to be multifocal and often require imaging for diagnosis, typically ultrasound or CT scans, to identify their presence and plan appropriate management, which may include antibiotics and drainage if necessary.
