Recurrent Liver Abscess in a Non-toxic Patient

Liver abscesses range in presentation from asymptomatic infection to sepsis. Recurrence is rare. We describe a case of an asymptomatic liver abscess that recurred 10 years after a previous abscess. The patient presented with flu-like symptoms and dark urine. Laboratory evaluation showed an elevation of aminotransferases and bilirubin. Triple-phase CT showed a 2.8 cm mass in the right liver lobe with linear enhancement. The abscess was aspirated, with cultures growing Escherichia coli. The patient was started on ceftriaxone and metronidazole and then discharged with outpatient follow-up. We describe an unusual case of asymptomatic pyogenic liver abscess growing E. coli, with the same location and causative organism as an abscess that occurred 10 years prior.
