title: Abdominal pregnancy with lithopedion formation presenting as a pelvic abscess.
abstract: BACKGROUND
  Abdominal pregnancy with lithopedion formation is rare and its presentation as a pelvic abscess has not been reported.
  
  
  METHODS
  A 38-year-old, gravida 1, para 0, presented with signs and symptoms of a pelvic abscess, which turned out to be a lithopedion from a 16-week abdominal pregnancy that had been terminated by a potassium chloride injection 2 years earlier. Intravenous antibiotics were followed by surgical removal of the lithopedion.
  
  
  CONCLUSIONS
  Pelvic abscess is an added complication of a lithopedion. Surgical removal to prevent such complications can be considered, balanced against the high operative risks.
