Background: Understanding of ovarian pregnancy is poor, because of the rarity of the condition. The exact etiology is unknown, preoperative diagnosis is a challenge, and clinical presentation is highly variable. Generally, ovarian pregnancies rupture later than tubal gestation, and there are reports of ovarian pregnancies continuing right up to the third trimester. Case: A case of very early rupture of an ovarian pregnancy on day 28 of the cycle, along with a review of the literature to determine usual gestation at the time of rupture of spontaneously conceived ovarian pregnancies, is presented. Results: Wedge resection of the left ovary with complete removal of ectopic gestation was performed, and postoperative recovery was uneventful. Histopathologic examination confirmed an ovarian pregnancy. Conclusions: Data collected in this report suggest that nearly three-fourths of spontaneously conceived ovarian pregnancies rupture at or after 8 weeks of gestation, which is higher than in previous reports. Rupture of ovarian pregnancy on day 28 of the cycle is very unusual, and a possible cause is discussed briefly. (J GYNECOL SURG 29:245)
