Rudimentary uterine horn pregnancy

Rudimentary uterine horn pregnancy refers to the implantation of a fertilized egg in the uterine horn at the junction of the uterus and the fallopian tube opening, where the embryo develops towards the uterine cavity rather than in the interstitial part of the fallopian tube. It is a relatively rare type of pregnancy in a special uterine location. The main symptoms include amenorrhea, abdominal pain, vaginal bleeding, and asymmetrical uterine enlargement.
