[Pleurisy in ovarian hyperstimulation syndrome. Apropos of a case].

The syndrome of ovarian hyperstimulation is a little known aetiology of pleural effusion. It should be thought of in young women who are under treatment to induce ovulation. Serous effusions which occur in these cases are a serious sign. The effusions are exudates and not transudates as occurs in Demons-Meigs syndrome. The treatment which will be undertaken ought to consider the possibility that a pregnancy is underway.
