MRI of Hepatic Abscesses

The infiltration of normal or diseased hepatic parenchyma by bacteria or microorganisms can result in a cavitated lesion, which is defined as a hepatic abscess. These microorganisms can enter into the hepatic parenchyma via the biliary system, hematogenously, or through direct contiguous spread from adjacent structures. In the Western world, pyogenic hepatic abscesses are the most prevalent form; in Southeast Asia and Africa, amebic hepatic abscesses are most common.1 Underlying biliary disease, comorbidities (e.g., diabetes, immunocompromised states), and severity of hepatic involvement are prognostic indicators.
