Two weeks before presentation, the patient was seen at an outside hospital reporting severe posterolateral pain on the right side of the neck and mild generalized abdominal pain. Preliminary laboratory evaluation results revealed a hemoglobin level of 8.0 g/dL (to convert to grams per liter, multiply by 10) and an increased human chorionic gonadotropin level of 1500 mIU/mL (conversion to international units per liter is 1:1). The obstetrics department was consulted and diagnosed an ectopic pregnancy of approximately 5 weeks' gestation after transvaginal ultrasonography failed to show intrauterine products of conception. The patient was taken to the operating room for diagnostic laparoscopy, and 600 mL of blood was evacuated from her pelvis; no ectopic pregnancy was visualized. The patient was then discharged home. At follow-up 1 week later, the human chorionic gonadotropin level remained elevated at 1600 mIU/mL prompting treatment with methotrexate sodium.
