Introduction: Partial molar pregnancy in non-communicating rudimentary horn of unicornuate uterus is
very rare. It often has catastrophic results. It may be missed as an early diagnosis unless it results in rupture
of the horn in the late 1st or early 2nd trimester. Pre rerupture diagnosis of rudimentary horn pregnancy
with USG is technically difficult with a poor sensitivity.
Case Presentation: We present a case of unruptured non-communicating rudimentary horn pregnancy at
7 weeks with live fetus presenting in our emergency department with pain in abdomen. Laparotomy was
carried out and excision of rudimentary horn was done. However, the histopathological reports were more
surprising suggesting to be a partial hydatidi form molar pregnancy in rudimentary horn. Beta-hCG report
w as 50,000 miu/ml. Serial Beta-hCG was done weekly till its values reached well within normal limits
after 10 weeks.

Conclusion: Development of partial molar pregnancy in a rudimentary horn is a very rare phenomenon.
High degree of clinical suspicion is required when ultrasound reports are inconclusive regarding intrauterine
pregnancy. Further close follow up of patient is required in future pregnancies to avoid recurrence of molar
