Pyogenic hepatic abscess: long resolution time despite adequate therapy.

: A 50-year-old male patient with a pyogenic hepatic abscess was successfully treated with an antibiotic regimen and percutaneous drainage of the abscess. Although this treatment was successful, it took more than 3 months for the abscess cavity to be completely resolved. A slow resolution of hepatic abscesses is therefore no evidence for the ineffectiveness of treatment.
