Mayer-Rokitansky-Küster-Hauser syndrome is a disorder affecting the female reproductive system, which can result in an absent uterus and vagina or a partially absent vagina with a normal uterus. While this female reproductive disorder can be difficult to diagnose, transabdominal sonography is often the initial imaging modality used to evaluate the female pelvis in this patient population as many females are not diagnosed with the disorder until primary amenorrhea is noted around puberty. This case study presents a young female who is diagnosed with an absent uterus and vagina but normal ovaries and discusses the role that sonography plays in diagnosing Mayer-Rokitansky- Küster-Hauser syndrome.
