  ABSTRACT: Hepatic abscesses can develop in association with biliary disease, through hematogenous spread via the portal circulation, by continuity with an intra-abdominal infection, as a post-surgical complication or sepsis, and can be either bacterial (pyogenic) or parasitic (usually amoebic). We present the case of an 80-year-old woman with sepsis and a hepatic abscess that on microbiologic culture, grew Peptostreptococcus anaerobius but with an unusual finding of abundant monosodium urate (MSU) crystals in the purulent material. There are case reports of gouty tophi presenting as liver nodules as a first manifestation of gout in patients with underlying hepatic disease. However, to the best of our knowledge, this is the first report of MSU crystals within a pyogenic hepatic abscess in a patient without gout. We review the characteristics of gouty tophi and compare them to those found in the abscess cavity, as well as conditions under which MSU crystals are formed.
