Abstract

Background: Interstitial ectopic pregnancy implants in the proximal intramural portion of the fallopian tube. It could rupture with associated massive hemoperitoneum which is life threatening. Diagnosis is usually made by ultrasound scan although this can be misinterpreted as intrauterine pregnancy. We report a case of interstitial ectopic gestation which was not diagnosed by ultrasound
scan but had laparotomy with metroplasty following clinical diagnosis. 

Case presentation: A 32 year old woman who presented with abdominal pain following 16 weeks of amenorrhoea. She also presented with an ultrasound report of a viable pregnancy at 16 weeks and 2 days gestation with associated haemoperitoneum. A clinical assessment of ruptured ectopic gestation was made and she had left salpingectomy with metroplasty. The postoperative period was
unremarkable and she was stable on follow up. 

Conclusion: Interstitial pregnancy which is a rare type of ectopic gestation could be a diagnostic challenge. Its rupture could be associated with massive blood loss and treatment is surgical.
