Pelvic abscess is a rare entity in pregnancy. The true etiology is uncertain but a flare-up of an old pelvic inflammatory disease is most likely. Usually, these patients undergo laparotomy and these abscesses are discovered incidentally, as described in our series. Surgical drainage and conservative surgical procedures under antibiotics are recommended during pregnancy albeit there is no consensus on patient management. Through this report, we aim to discuss this clinical entity and to underline the importance of patient management in case of its diagnosis. Copyright (C) 2002 S. Karger AG, Basel.
