A Silent Rupture of Extra Horn of Bicornuate Uterus, Due to Molar Pregnancy

Molar pregnancy is an abnormality in chorionic villi that cause trophoblastic proliferation and edema of villous stroma. Ectopic molar preganancy is a very rare entity. Unicornuate uterus with rudimentary horn occurs due to failure of complete development of one of the mullerian ducts and incomplete fusion with contralateral side. Pregnancy in non communicating rudimentary horn is extremely rare and usually terminates in rupture during first and second trimester of pregnancy. Variable thickness of rudimentary horn musculature, poor distensibility of myometrium lead to rupture. Diagnosis of rudimentary horn is difficult and can be missed in ultrasonography. This report literature is replite with a unique case report of ruptured horn of bicornuate uterus in case of complete molar pregnancy, a rare and unreported occurrence so far.
