A rare case of an ectopic pregnancy in the rudimentary tube of a patient with an isolated unicornuate uterus.

Uterine anomalies are relatively uncommon and go undiagnosed in many cases. Ectopic pregnancies have been reported in such patients, although rarely, in the non-communicating rudimentary horns of unicornuate uteri. However, the case presented is of an ectopic pregnancy in the rudimentary fallopian tube related to an undescended ovary in a patient with an isolated unicornuate uterus, a phenomenon which is extremely rare.
