Abstract

Mayer- Rokitansky- Kuster- Hauser (MRKH) syndrome is a rare entity characterized by congenital aplasia of the uterus and the upper part of 2/3rd of vagina in normal karyotype females with normal development of secondary sexual characteristics. The incidence rate is about 1 in every 4500 females. We report a case series of three different patients who presented with different clinical picture to various outpatient departments of our hospital. Magnetic Resonance Imaging of the pelvis was done in all these patients.

Introduction

Mayer–Rokitansky-Kuster-Hauser syndrome is a very rare condition and the varying presentation of this entity often presents a diagnostic challenge [1]. But meticulous radiological assessment of the patient not only provides early and precise diagnosis but also helps in classifying the types of this syndrome, thus providing a skillful surgical approach. MRKH may be isolated (type I) but more frequently associated with renal, vertebral, auditory and cardiac defects (MRKH type II or MURCS association). The majority of are sporadic; however review of literature also demonstrates few cases depicting the familial nature of the disease. The mode of inheritance is autosomal dominant with an incomplete degree of penetrance and variable expressivity. Type II MRKH is more frequent than Type 1 MRKH [1]. We, hereby, present a case series of Mayer–Rokitansky-Kuster-Hauser syndrome in phenotypically normal female patients presenting with complaints of primary amenorrhea diagnosed on 1.5 Tesla MRI studies.

Cases

4.1 A 14 years female patient presented with complaints of abdominal pain. There was no history of fever, urinary complaints, swelling or lump in abdomen or history of any prolonged drug intake. On further enquiry it was revealed that patient has not achieved menarche yet. On clinical examination, the height was normal, secondary sexual characteristics were normal for age. The ultrasound examination of pelvis which revealed non visualization of uterus within the uterine fossa. For further evaluation and characterization, MRI pelvis was performed which confirmed the empty uterine fossa with no evidence of any abnormal increased signal intensity or mass lesion in the area with evidence of visualization of normal bilateral ovaries. So, the diagnosis of MEYER ROKITANSKY KUSTER HAUSER SYNDROME (TYPE I) was made (Figure 1).

1.2 A 10 years female patient presented with complaints of abdominal pain off and on with failure to thrive. Patient had not achieved menarche. No other relevant findings were noted. On sonography of pelvis region, no definite evidence of visualization of uterus within the uterine fossa was noted. Thus, MRI pelvis was performed which confirmed the presence of empty uterine fossa with no evidence of visualization of ovaries. So, the diagnosis of MEYER ROKITANSKY KUSTER HAUSER SYNDROME (TYPE II) was made (Figure 2).

1.3 A 22 years female patient presented with complaints of primary amenorrhea. There was no significant past history. Clinical examination was normal. The patient was then subjected to ultrasound pelvis examination which revealed non visualization of uterus within the uterine fossa. For further evaluation and characterization, MRI pelvis was performed which confirmed the presence of empty uterine fossa with no evidence of any abnormal increased signal intensity or mass lesion within it and no evidence of visualization of ovaries. Also noted was the presence of fusion of bilateral kidneys seen located in pelvis region suggestive of pancake kidney confirming the diagnosis of MEYER ROKITANSKY KUSTER HAUSER SYNDROME (TYPE II) with associated renal anomaly (Figure 3).

Genetic evaluation of these patients revealed normal karyotype i.e. 46,XX.

Discussion

The Mayer- Rokitansky-Küster-Hauser (MRKH) syndrome or Rokitansky syndrome is a congenital malformation of the female genital tract and is the second most frequent cause of primary amenorrhea after gonadal dysgenesis. It is characterized by vaginal atresia, and uterine/tubal abnormalities including absence or hypoplasia of the uterus and fallopian tubes [1,2]. The patients have normal karyotype 46,XX and normal secondary sexual characteristics, as the ovaries are present and functional, but menstruation is absent. It occurs due to interrupted embryonic development of the Müllerian ducts at about 7 weeks after fertilization. The fallopian tubes, uterus, cervix and upper ¾ of vagina develop from Müllerian ducts usually develop between 8th to 12^th gestational weeks [3]. Any developmental defect occurring at this stage leads to agenesis of Mullerian structures. Concomitantly, the development of kidneys, ureter, and bladder occurs between 6^th to 12^th weeks of gestation. There are two different forms of this syndrome: the typical form of this syndrome (type I) is characterized by congenital absence of the uterus and upper vagina with normal ovaries and fallopian tubes [4]. Secondly, the atypical form (type II) of the syndrome includes associated abnormalities of the ovaries and fallopian tubes and renal or vertebral anomalies. Renal anamolies are seen in 30-40% of the cases however, only 10% of the cases are associated with vertebral anomalies. Renal malformations include: unilateral agenesis, horseshoe kidney, renal hypoplasia, ectopic kidneys and hydronephrosis [4].

High Resolution Sonography of pelvis helps in initial evaluation and assessment of the disease. Magnetic resonance imaging is the most sensitive and specific imaging modality in the evaluation of this syndrome. It provides acquisition of multiplanar images with or without fat saturation. It acts as a good predictor in evaluation of various anatomical alterations such as uterine agenesis, as well as evaluating ovaries, vagina and associated anomalies [2]. Laparoscopic examination of the pelvis can be helpful in cases where the evaluation of patients by different imaging modalities is uncertain. The final diagnosis and classification is made by correlating the findings of imaging and karyotyping. The treatment is usually multimodal because explanation of the disease process to the parents and the patient generates great amount of anxiety and psychological stress. In almost all the patients’ creation of neovagina is required. This can be achieved surgically and sometimes nonsurgically. Vaginoplasty allows these patients to have a normal sex life and avoid the risk of physchological trauma. Whenever surgical approach is chosen, consideration should be given to excision of uterine remnants to avoid risk of endometriosis in future life [5,6].

Conclusion

MRI is a useful tool which can help in diagnosis and proper management of this rare syndrome.
