Bilateral Mature Cystic Teratoma Masquerading as an Ectopic Pregnancy: A Case Report and Review of the Literature

Abstract

Abstract Background: The presentation of an adnexal mass with a raised beta–human chorionic gonadotropin (β-hCG level) does not necessarily indicate a diagnosis of ectopic pregnancy. This article highlights an unusual case of benign cystic teratomas with β-hCG production, mimicking the presentation of an ectopic pregnancy. Case: A 28-year-old woman who had a 10-week period of amenorrhea presented with an acute abdomen and an increased β-hCG level. An ultrasound scan revealed features suggestive of an ectopic pregnancy. Results: The patient underwent right salpingo-oophorectomy (for torsion of an ovarian cyst) and a left cystectomy (for an ovarian cyst). There was no evidence of an ectopic pregnancy found during the surgery. Histopathology examination reported that she had bilateral mature cystic teratomas. Conclusions: Careful assessment and consideration of ovarian accidents or neoplasms is crucial, especially in the presence of an ovarian mass with an increased β-hCG level. (J GYNECOL SURG 20XX:000)
