Partial bicornuate uterus

Case contributed by Mohammad Taghi Niknejad
Diagnosis almost certain

Presentation

Workup for primary infertility.

Patient Data

Age: 30 years
Gender: Female
Fluoroscopy

The upper part of the endometrial cavity is divided and the lower part extends to the internal cervical os. Each endometrial horn leads to a separate fallopian tube and normal contrast spillage is evident from both tubes.

Case Discussion

On the hysterosalpingogram, It is difficult to differentiate between septate and bicornuate anomalies since the uterine fundal contour is not visible. However, an angle of less than 75° between the uterine horns is suggestive of a septate uterus while an angle of more than 105° is more consistent with a bicornuate uterus.  Usually, further evaluation with ultrasonography or MRI is needed for a definite diagnosis.
