ABSTRACT
A 43-year-old woman presented with a 10-day history of lower abdominal pain and two days of vaginal bleeding. Ultrasonography showed a sac-like structure within the endocervical canal. The structure had a thick echogenic rim. No foetal heartbeat was seen. Intramuscular methotrexate was given and evacuation of the uterus yielded a small amount of tissue which was revealed histologically as products of conception, confirming the diagnosis of a cervical ectopic pregnancy. The clinical and imaging features of cervical ectopic pregnancy are highlighted.
