[Spontaneous hyperstimulation of the ovaries with luteal cysts and ascites during a twin pregnancy-extreme case of the syndrome of painfull early pregnancy (author's transl)].

Laparotomy was performed in a para II gravida II of 28 years in an early twin pregnancy. The left ovary was enlarged to 18 X 8 cm, the right ovary to 1i X 8 cm by luteal cysts. The abdominal cavity contained an ample amount of peritoneal fluid. The history is understood as spontaneous ovarian hyperstimulation, and as an extreme case of the relatively common syndrome of painfull early pregnancy, occasionally leading to unnecessary surgical intervention.
