Abstract

Retroperitoneal pregnancy is an extremely rare type of ectopic pregnancy, accounting for less than 1% of all ectopic cases, and poses significant challenges in both diagnosis and management. We present the case of a 34-years - old female patient with history of bilateral salpingectomy admitted to our hospital 40 days after embryo transfer. At the time of admission, β-hCG level was 11,664 IU/L; however, no gestational sac was identified on transvaginal sonography. A computed tomography scan suggested an abnormal mass lying between the abdominal aorta and the inferior vena cava, raising suspicion of a retroperitoneal pregnancy. The patient initially underwent multi-dose methotrexate treatment and laparoscopic surgery was performed to excise the ectopic mass. The postoperative course was uneventful, and her β-hCG level returned to negative after four weeks. A review of literature indicates the rarity of retroperitoneal pregnancy, which often presents without specific symptoms, complicating early diagnosis. The location of the ectopic mass further complicates therapeutic approaches. Surgical intervention remains the mainstay of treatment, offering definitive management and favorable clinical outcomes.
