Objective:
To describe a case of a unicornuate uterus with a normal external uterine morphology.
Design:
Case report.
Setting:
University-based fertility center.
Patient(S):
A 30-year-old nulligravid woman with a 1-year history of infertility found to have a right proximal tubal occlusion on hysterosalpingogram.
Intervention(S):
Laparoscopy, hysteroscopy, and magnetic resonance imaging.
Main Outcome Measure(S):
External and internal morphology of the uterus.
Result(S):
Laparoscopy showed a normal external uterine morphology and normal fallopian tubes and ovaries, but chromopertubation failed to demonstrate a fill and spill from the right fallopian tube. Hysteroscopy showed a single tubular uterine cavity projecting to the left with a single left tubal ostium, consistent with a unicornuate uterus. Magnetic resonance imaging confirmed a normal external uterine fundal contour and an internal uterine morphology consistent with a unicornuate uterus.
Conclusion(S):
This is the first reported case of a unicornuate uterus presenting with a normal external uterine morphology and an internal morphology consistent with a unicornuate uterus, and we propose inclusion of this anomaly in the classification of mullerian anomalies.
