Case contributed by Dr Mohammad A. ElBeialy

Presentation

Primary amenorrhea.

Patient Data

Age: 20 years
Gender: Female
MRI

Complete absence of the uterus as well as a rudimentary vagina.  No ovarian tissue is identified.  

Case Discussion

Complete absence of the uterus as well as scanned upper vagina with rudimentary vaginal pouch on clinical examination. No ovarian tissue was identified on the MRI examination. No ectopic testicular tissue was identified within the scanned pelvis or within the inguinal canals or the perineum. Androgen insensitivity syndrome (male pseudohermaphroditism) was suggested and the patient had undergone karotyping that proved to be male 46 XY karyotype.

The differential diagnosis is Mayer-Rokitansky-Kuster-Hauser syndrome where the uterus is rudimentary or absent as well, however with female karyotype and almost normal female genitalia, and normal ovaries identified at imaging by US or MRI.
