A 45-year-old woman admitted to our hospital complaining of perimenopausal uterine bleeding not responding
to medical treatment. Ultrasound evaluation revealed unicornuate uterus with adenomyosis and it was so difficult
to see the distant small left rudimentary horn on ultrasound. The patient underwent laparotomy with total
hysterectomy for both horns and was sent to pathologist that indicated adenomyosis and non-communicating
non-cavitated left rudimentary horn.
