Presentation
Infertility. History of ectopic pregnancy.
Patient Data
There are two endometrial cavities with a large intercornual distance.
MRI shows a fibromuscular septum dividing the uterine cavity. There is no fundal cleft.
Incidental left ovarian hemorrhagic cyst with fluid level showing dependent low signal fluid content.
Case Discussion
In this case, even though HSG showed a large interconuate distance, which is more common in bicornuate uterus. MRI showed a fibromuscular septum dividing the uterine cavity and no fundal cleft consistent with a septate uterus.
MRI is considered the current imaging modality of choice in the differentiation between bicornuate and septate uterus.
