MRI for Primary Amenorrhea

What is it about?

This study investigated the etiology of primary amenorrhea and the role of MRI in its diagnosis and management. The main factors identified were Müllerian duct anomalies (MDAs) and gonadal dysgenesis. MRI was effective in visualizing the anatomical details of MDAs, such as Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome, distal vaginal obstruction (DVO), and obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome. It provided accurate evaluation of the uterus, ovaries, and associated structures. In cases of gonadal dysgenesis, MRI helped exclude malignancy. The findings highlight the importance of MRI in determining the etiology and guiding appropriate treatment for primary amenorrhea.

Why is it important?

Primary amenorrhea is a significant condition with physical, social, and psychological implications, particularly in adolescents. It is crucial to determine its underlying cause for appropriate management. Gonadal dysgenesis and Müllerian duct anomalies (MDAs) are commonly implicated factors. This study found MDAs (58.83%) and gonadal dysgenesis (41.17%) to be the main etiologies. MRI was effective in diagnosing and assessing the anatomical details of MDAs, such as Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome, distal vaginal obstruction (DVO), and obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome. It allowed evaluation of the uterus, ovaries, and associated structures accurately. In gonadal dysgenesis cases, streak gonads were not visualized on MRI, but the absence of malignancy was confirmed. Overall, MRI plays a crucial role in determining the etiology, planning surgery, and ensuring appropriate management in cases of primary amenorrhea.
