title: Multiple large pyogenic liver abscesses of the tropics: a new entity.
abstract: BACKGROUND
  Pyogenic liver abscesses most commonly occur in males in -he sixth decade, are usually associated with biliary tract disease, malignancy and immunosuppression and the mortality rate is high. We describe another form of pyogenic abscess occurring in females which, if treated aggressively, carries a much better prognosis.
  
  
  METHODS
  Between 1986 and 1993 we treated 8 patients with multiple pyogenic liver abscesses. Diagnosis was established by ultrasound and CT scan followed by needle aspiration to confirm pus. Amoebic aetiology was excluded by a serology, poor response to metronidazole and biopsy of the abscess wall.
  
  
  RESULTS
  The mean age of our patients was 30 +/- 7 years and there were 2 males and 6 females. They presented with fever and abdominal pain for more than 2 months, tender hepatomegaly, a raised ESR and alkaline phosphatase. US and CT scans showed multiple large abscesses in the right lobe. Histology suggested chronic inflammation and with no definite organism isolated except for visceral larva migrans in one case. All patients underwent surgery--deroofing with drainage was done in four, segmental hepatic resection in three and right hepatectomy in one. One patient had a recurrence and underwent repeated resection. Only one patient died and 7 did well with no recurrence at a mean followup of 24 +/- 27 months.
  
  
  CONCLUSIONS
  Large multiple cryptogenic pyogenic abscesses of the liver occurring mostly in young females, which respond well to aggressive excisional surgery may constitute a distinct clinical entity.
