Presentation
History of recurrent abortion
Patient Data
Uterus is normal in size, anteverted and anteflexed. Two endometrial cavities are seen at the level of uterine fundus. Coronal oblique STIR MR images show the presence of clear fundal cleft which is a reliable indicator for fusion anomalies such as bicornuate uterus.
Sagittal T2 MR images reveal normal uterine cervix and well visualization of myometrial zonal anatomy.
Bilateral ovaries are normal in volume and MR appearance.
Case Discussion
Bicornuate uterus is due to incomplete or partial fusion of the müllerian ducts and accounts for approximately 10% of Mullerian duct anomaly. It is characterized by the presence of a cleft (>1 cm in depth at MR imaging) in the external contour of the uterine fundus. The duplicated endometrial cavity may be associated with cervix duplication (bicornuate bicollis) or be without cervix duplication (bicornuate unicollis).
