The Bottom Line: Most cases of hepatic abscess present at advanced age. One study reported a mean age > 57 years.19 This finding suggests that older individuals are more susceptible to bacterial infection and thus abscess formation. Most of the symptoms of hepatic abscess are due to infection and are nonspecific and it can be quite difficult to diagnose in a timely manner. The most commonly reported signs and symptoms (Table 2. Page 162) include fever in most but not all cases, abdominal pain, and hypotension

Hepatic abscess remains a serious and often difficult to diagnose problem. HAs can be divided into three main categories based on the underlying conditions: infectious, malignant, and iatrogenic. Infectious abscesses include those secondary to direct extension from local infection, systemic bacteremia, and intra-abdominal infections that seed the portal system. Hepatic abscess can be defined as an encapsulated collection of suppurative material within the liver parenchyma, which may be infected by bacterial, fungal, and/or parasitic micro-organisms
