RationaleRectal ectopic pregnancy is an extremely rare abdominal pregnancy. This article presents a female underwent an unsuccessful in vitro fertilization which was misdiagnosed by serum beta-human chorionic gonadotropin (β-hCG) test and transvaginal ultrasonography. Twenty days later, a ruptured rectal ectopic pregnancy was confirmed by laparoscopy then the gestational tissue removed successfully.Patient ConcernsA 32-year-old Chinese female was admitted to our hospital with complaining of symptoms, like gradual worsening of lower abdominal pain and dysuria. The abdominal ultrasonography revealed a sac-like mass in the posterior area to the uterus and a moderate amount of free fluid in the pelvic cavity. Forty days ago, she underwent a frozen embryo transfer. Twenty days ago, her serum β-hCG level was <5 mIU/mL and neither intrauterine nor ectopic pregnancy was detected by transvaginal ultrasonography. Then the procedure was thought to have resulted in biochemical pregnancy failure.DiagnosisThe primary rectal ectopic pregnancy.InterventionsThe mass was removed laparoscopic surgery.OutcomesThe patient recovered well.LessonsWhen the history of in vitro fertilization combined with an inappropriate rise of serum β-hCG and no visible evidence of an intra-uterine pregnancy, physicians should consider the possibility of abdominal pregnancy. Early diagnosis of abdominal pregnancy can effectively save the life of the pregnant woman.Copyright © 2022 the Author(s). Published by Wolters Kluwer Health, Inc.
