Liver abscesses are an entity that sets out a diagnostic challenge with a severe clinical course and non-negligible mortality. Their origin is usually bacterial (>80%), parasitic, mixed or, more rarely, fungal. We present the case report of a 45-year-old man, native of Ghana, with no relevant medical-surgical history, was admitted for septic shock with multiple organ dysfuntion syndrome. Complementary imaging tests revealed a liver abscess in segments IV and VII measuring 60x45x54 mm, so antibiotic treatment with piperacillin-tazobactam was started and a pigtail drainage was placed. In blood cultures, the microorganism parvimonas micra (anaerobic gram-positive cocci) was isolated with high degree of sensitivity rates to penicillin, clindamycin and metronidazole. Treatment was de-escalated to clindamycin until completing 4 weeks of intravenous treatment. Control CT showed a decrease in the size of the abscess and pigtail drainage was removed.
