title: Ruptured interstitial ectopic pregnancy at 18 weeks gestation diagnosed by MRI: a case report.
abstract: Ectopic pregnancy in the interstitial part of the fallopian tube is a rare event, associated with a high rate of complications due to delayed diagnosis. Rupture of such pregnancy often results in catastrophic hemorrhage. Several reports highlighted the role of magnetic resonance imaging in establishing the diagnosis of interstitial pregnancy, but magnetic resonance imaging findings of a ruptured advanced interstitial ectopic pregnancy have not been published before. The authors therefore present characteristic findings on magnetic resonance imaging of a ruptured interstitial ectopic pregnancy which had reached 18 weeks, in a 25-year-old woman who presented with acute abdominal pain.
