Cervical ectopic pregnancy is a rare form of ectopic pregnancy. This incidence represents less than 1% of all ectopic pregnancies with reported incidence rates varying from 1:1,000 to 1:95,000 pregnancies. Cervical ectopic pregnancy is difficult to diagnose. Hydronephrosis and hydroureter have never been reported as complications of cervical ectopic pregnancy, and both are diagnosed after laparotomy. The potential morbidity, highlighted in this case study, demonstrates the importance of early diagnosis of a cervical ectopic pregnancy so that early intervention and treatment can be employed.
