Overview
There are no MRI findings associated with amenorrhea. However, a MRI may be helpful in the diagnosis of the diseases that can cause amenorrhea, such as polycystic ovary syndrome (PCOS), androgen insensitivity syndrome, anatomic genital defects, and also pituitary adenoma.

Polycystic ovary syndrome (PCOS)
- Rotterdam criteria is diagnostic of polycystic ovary syndrome (PCOS). Rotterdam criteria uses ultrasound findings which include:[4]
Androgen insensitivity syndrome
- Findings on an MRI suggestive of androgen insensitivity syndrome include:[6]
- Bilateral cryptorchidism
- Juxta-testicular Mullerian duct cysts
- Absent or rudimentary uterus
Anatomic genital defects
- Findings on an MRI suggestive of imperforate hymen include:[7]
- Hypoechoic mass in the vagina (hematocolpos) and enlarged uterus (haematometra)
- Normal ovaries
- Findings on an MRI suggestive of transverse vaginal septum include:
Pituitary adenoma
- Brain MRI may be helpful in the diagnosis of the cause of amenorrhea. Findings on MRI suggestive of amenorrhea include:[8]
- Hypothalamo-pituitary lesions
- Optic nerve compression (pituitary adenoma)
- Inner ear abnormalities (CHARGE syndrome)
- Brain MRI is indicated in patients with amenorrhea, experiencing some alarm signs, such as headache, visual impairment, and behavioral changes.
