Splenic rupture during pregnancy is considered a catastrophic condition associated with high maternal and fetal mortality and morbidity. Herein, we report a case of severe preeclampsia that underwent cesarean delivery with subsequent spontaneous splenic rupture. A 21-year-old primigravid woman was transferred to our center due to severe preeclampsia that underwent cesarean delivery because of uncontrolled blood pressure and low platelet count. She developed coffee ground vomiting postoperatively and clinical evidence of free fluid was present. Emergency laparotomy was performed and revealed an approximately 2.5–3 cm defect in splenic capsule with active bleeding from the ruptured site. The site of splenic laceration was packed with gauze. Postoperative period was uneventful and she was discharged on day 15 after admission. As spontaneous splenic rupture is associated with severe complications, its differential diagnosis should be kept in mind in pregnant women with severe preeclampsia.
