Magnetic resonance imaging revealed three patterns of uterine remnants in Mayer-Rokitansky-Küster-Hauser syndrome, with unilateral rudimentary uteri showing larger volumes and higher rates of endometrium, haematometra, ovarian endometriosis, and pelvic pain.

This retrospective, single-institution MRI study reviewed pelvic magnetic resonance images and records of 92 patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome to classify uterine involvement into uterine agenesis, unilateral rudimentary uterus, and bilateral rudimentary uteri, and to compare uterine volume, presence of endometrium, ovarian location, endometriosis, and pelvic pain across groups. Patients with unilateral rudimentary uteri had larger mean uterine volumes and higher incidences of endometrium (100% vs 22%), haematometra (56% vs 3%), and ovarian endometriosis (22% vs 3%) compared with bilateral rudimentary uteri; ectopic ovaries were observed in 38% overall. Pelvic pain was reported more often in the unilateral rudimentary uterus group (56%) than in those with no remnants (5%) or bilateral remnants (14%). The authors note a key limitation that the analysis is observational and performed retrospectively in one institution. Relevance to endometriosis: the paper specifically quantifies ovarian endometriosis and relates it to MRI-detected patterns of uterine remnants in MRKH patients, though the study’s main focus is characterizing uterine/anatomic patterns and clinical settings in MRKH rather than endometriosis as a primary disease.

Abstract

OBJECTIVE: To characterize the anatomical features and clinical settings of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome and correlate them with patterns of uterine involvement. METHODS: Pelvic magnetic resonance images and medical records of 92 MRKH patients were retrospectively reviewed. Patients were subgrouped by uterine morphology: uterine agenesis, unilateral rudimentary uterus and bilateral rudimentary uteri. Uterine volume, presence of endometrium, location of ovary, endometriosis and pelvic pain were compared among groups. RESULTS: The mean uterine volume was 33.5 ml (17.5-90.0 ml) for unilateral uterine remnants, and 16.1 ml (3.5-21.5 ml) for bilateral uterine rudiments (p<0.01). The incidence of presence of endometrium (100% vs. 22%, p<0.001), haematometra (56% vs. 3%, p<0.001) and ovarian endometriosis (22% vs. 3%, p<0.01) was significantly increased in the group of unilateral rudimentary uteri as compared with the group of bilateral uterine remnants. Thirty-one patients (38%) showed ectopic ovaries. Pelvic pain was more common in individuals with unilateral rudimentary uterus than those who had no (56% vs. 5%, p<0.01) or bilateral uterine remnants (56% vs. 14%, p<0.05). CONCLUSION: MRKH patients with different patterns of uterine involvement may have differentiated anatomical features and clinical settings. KEY POINTS: • Rudimentary uteri, especially bilateral rudimentary uteri, were quite common in MRKH syndrome. • Uterine remnants can be relatively large, especially the unilateral rudimentary uterus. • Presence of endometrium and related complications are not rare in MRKH syndrome. • Existence of endometrium and complications are more frequent in unilateral rudimentary uterus.

Abstract

Objective To characterize the anatomical features and clinical settings of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome and correlate them with patterns of uterine involvement.

Methods

Pelvic magnetic resonance images and medical records of 92 MRKH patients were retrospectively reviewed. Patients were subgrouped by uterine morphology: uterine agenesis, unilateral rudimentary uterus and bilateral rudimentary uteri. Uterine volume, presence of endometrium, location of ovary, endometriosis and pelvic pain were compared among groups.

Results

The mean uterine volume was 33.5 ml (17.5–90.0 ml) for unilateral uterine remnants, and 16.1 ml (3.5–21.5 ml) for bilateral uterine rudiments (p<0.01). The incidence of presence of endometrium (100% vs. 22%, p<0.001), haematometra (56% vs. 3%, p<0.001) and ovarian endometriosis (22% vs. 3%, p<0.01) was significantly increased in the group of unilateral rudimentary uteri as compared with the group of bilateral uterine remnants. Thirty-one patients (38%) showed ectopic ovaries. Pelvic pain was more common in individuals with unilateral rudimentary uterus than those who had no (56% vs. 5%, p<0.01) or bilateral uterine remnants (56% vs. 14%, p<0.05).

Conclusion

MRKH patients with different patterns of uterine involvement may have differentiated anatomical features and clinical settings. Key Points • Rudimentary uteri, especially bilateral rudimentary uteri, were quite common in MRKH syndrome. • Uterine remnants can be relatively large, especially the unilateral rudimentary uterus. • Presence of endometrium and related complications are not rare in MRKH syndrome. • Existence of endometrium and complications are more frequent in unilateral rudimentary uterus.
