Ovarian torsion and spontaneous ovarian hyperstimulation syndrome in a twin pregnancy: A case report.

Introduction: Ovarian hyperstimulation syndrome (OHSS) is extremely rare in spontaneous pregnancies. Spontaneous OHSS can result from glycoprotein hormones stimulating follicle-stimulating hormone receptors (FSHR).

Presentation Of Case: We report a twin pregnancy in which ovarian torsion and hemoperitoneum complicating OHSS were treated with left adnexectomy and aspiration.
