Spontaneous ovarian hyperstimulation syndrome in a normal singleton pregnancy.
OBJECTIVE
It is known that most cases of ovarian hyperstimulation syndrome (OHSS) are associated with the therapies for ovulation induction. However, OHSS may rarely be associated with a spontaneous ovulatory cycle, usually in the case of multiple gestations, hypothyroidism or polycystic ovary syndrome.


METHODS
A case of OHSS in a woman who became pregnant naturally and who had no underlying disease is presented here. The patient was managed expectantly with no complications.


CONCLUSIONS
Although spontaneous ovarian hyperstimulation is a rare entity, it is important to differentiate it from other causes of ovarian enlargement. Occasionally, life-threatening situations may occur, but it is usually a self-limiting process.
