Review Article : Ectopic gestational-sac encapsulated in an ovarian cyst: A case report

Ovarian pregnancy is a rare and life-threatening condition accounting for 0.63% of all ectopic gravidae. In this case report, we present a 30-year-old woman with gravida 3; para 2 + 0 (2 alive) who attended our facility for a routine ultrasound scan. She complained of non-acute abdominal pain with no vaginal bleeding; she had a positive β -HCG test (Beta Human Chorionic Gonadotropin). Ultrasonography revealed a huge left ovarian mass 49mm in diameter, with an embedded decidua of a gestational sac 20mm, and a live foetal pole with a Crown-Rump Length (CRL) of 11mm corresponding to 7weeks + 1-day gestational age. Oophorectomy later confirmed the ultrasonographic diagnosis of ovarian pregnancy. Ovarian pregnancy is an uncommon but serious condition that requires fast intervention to prevent rupture and massive haemorrhage. This case shows that early diagnosis, ectopic-variation awareness, intervention and patient counselling would ultimately improve maternal health outcomes in women of reproductive age.
