A Rare Cause of Pelvic Pain: Degenerated Myoma Within a Rudimentary Horn of Unicornuate Uterus

Introduction: Treatment options for the different congenital uterine abnormalities of the uterus vary considerably; therefore, preoperative imaging plays a crucial role in the management. Case Report: A 29-year-old woman who had pelvic pain and vomiting, were examined with pelvic ultrasound (US) and magnetic resonance imaging (MRI). A hypoechoic pelvic mass was detected via ultrasound. A degenerated myoma was estimated, but to exclude a mass from the right ovary, a pelvic MRI was performed. The degenerated myoma was considered and was located in the rudimentary horn of the right side of the uterus. This appearance was confirmed by laparotomy.Conclusion: Although ultrasound is the first imaging modality for acute pelvic pathologies, magnetic resonance imaging is superior to ultrasound in evaluating the congenital abnormalities of the uterus
