Mayer-Rokitansky-Küster-Hauser Syndrome With Concurrent Adenomyosis and Leiomyoma in Rudimentary Uterus: A Case Report

Mayer–Rokitansky–Küster–Hauser Syndrome With Concurrent Adenomyosis and Leiomyoma in Rudimentary Uterus: A Case Report Funding: This work was supported by the National Health Commission of the People's Republic of China (IHECC-2022C20004). ABSTRACT We report a rare case of Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome accompanied by simultaneous adenomyosis and leiomyoma in rudimentary uterine remnants. A 35-year-old woman presented with progressive lower abdominal pain and underwent diagnostic imaging. The initial ultrasound erroneously suggested an adnexal mass, but subsequent imaging revealed bilateral uterine remnants—one with adenomyotic changes and the other harboring a leiomyoma. Laparoscopic excision confirmed these pathological findings. This case suggests the importance of regular gynecological imaging examinations for MRKH patients and challenges the conventional belief in the non-functional nature of Müllerian remnants. Furthermore, our findings underscore the diagnostic utility of transabdominal ultrasound in accurately identifying complex uterine anomalies.
