Presentation
6 week history of amenorrhea presented with bleeding PV. She had one living child and a history of recurrent 1st trimester spontaneous abortion.
Patient Data
USG pelvis revealed endometrium in the region of body of uterus bifurcating cranially into two horns with intervening tissue consistent with normal myometrium. Single gestational sac with a fetal pole of 6 weeks 6 days gestational age was present. No fetal cardiac activity was seen. She subsequently had a spontaneous complete abortion. HSG done in subsequent month confirmed the finding of a bicornuate uterus (not shown here).
Case Discussion
Bicornuate uterus accounts for approximately 10% of all congenital uterine anomalies.
The importance of identifying and distinguishing from a septate uterus is important as far as management modality and prognosis is concerned.
Criteria for bicornuate uterus include
- intercornual angle >75-105 degrees
- intercornual distance >4 cm
- fundal depression depth >1 cm
MR is nearly 100% accurate.
