The clinical
relevance of anatomical variants!. Sagittal transabdominal US image shows an elliptical echogenic mass, which represents the vaginal cavity markedly distended with blood products (haematocolpos). The uterus extends from the superior aspect of the mass.
![](https://pacs.de/sites/default/files/pictures/thumbs/data.pacs.de/1/3/3/0/4/9/000002_thumb.jpg)
The clinical
relevance of anatomical variants!. Transverse transabdominal US image shows uterus didelphys, with two uterine horns and two separated endometrial cavities.
![](https://pacs.de/sites/default/files/pictures/thumbs/data.pacs.de/1/3/3/0/5/0/000003_thumb.jpg)
The clinical
relevance of anatomical variants!. MR image shows a dilated hemivagina whose content has signal characteristics of blood, forming a blind-ending pouch secondary to obstruction.
![](https://pacs.de/sites/default/files/pictures/thumbs/data.pacs.de/1/3/3/0/5/1/000004_thumb.jpg)
The clinical
relevance of anatomical variants!. A large haematocolpos centrally (arrow), a finding that corresponds to the obstructed right hemivagina. Mild dilatation of the right endometrial cavity and a nondistended left endometrial cavity are also seen.
![](https://pacs.de/sites/default/files/pictures/thumbs/data.pacs.de/1/3/3/0/5/2/000005_thumb.jpg)
The clinical
relevance of anatomical variants!. Coronal T2-weighted image of a uterus didelphys, obtained in plane with the uterus, shows two widely divergent uterine horns (arrows) separated by a deep fundal cleft.
![](https://pacs.de/sites/default/files/pictures/thumbs/data.pacs.de/1/3/3/0/5/3/000006_thumb.jpg)
The clinical
relevance of anatomical variants!. Coronal fast spin-echo T2-WI shows a solitary left kidney, confirming renal agenesis with bowel loops in the right renal fossa, which is ipsilateral to the obstructed hemivagina.
![](https://pacs.de/sites/default/files/pictures/thumbs/data.pacs.de/1/3/3/0/5/4/000007_thumb.jpg)
The clinical
relevance of anatomical variants!. Transverse oblique T2-WI obtained with fat suppression demonstrate communication of the right uterine horn (curved arrow) with the dilated left hemivagina (arrow); the appearance of the left uterine horn is normal.

Müllerian
duct anomalies • Mayer-Rokitansky-Küster-Hauser syndrome - Ganzer Fall bei Radiopaedia
There are many classification systems for congenital utero-vaginal anomalies. These include:
- Buttram and Gibbons classification
- American Fertility Society (AFS) classification
- Modified Rock and Adam - AFS classification
Modified Rock and Adam - AFS classification
This classification divides congenital uterine anomalies into four main types:
- class I: dysgenesis of Müllerian ducts
- includes agenesis or hypoplasia of the müllerian duct derivatives: the uterus and upper two-thirds of the vagina
- the most common form is the Mayer-Rokitansky-Kuster-Hauser syndrome which is the combined agenesis of the uterus, cervix, and upper portion of the vagina
- class II: disorders of vertical fusion
- these anomalies are due to failure of fusion of the müllerian system with the sinovaginal bulb
- they include cervical dysgenesis and obstructive and nonobstructive transverse vaginal septa
- class III: disorders of lateral fusion
- describes anomalies that result in a duplicated or partially duplicated reproductive tract
- these disorders are due to impaired fusion and/or septal resorption of fusing Müllerian ducts attempting to form the uterus, cervix, and upper vagina
- it includes anomalies due to failure of fusion of the paired müllerian ducts (as in didelphic and bicornuate uteri) and failure of midline septum resorption after fusion (as in septate uterus)
- disorders due to lateral fusion defects are further subclassified into
- a: symmetric non-obstructive forms seen in five types: unicornuate, bicornuate, didelphic, septate, and DES-related uteri
- b: asymmetric obstructive forms seen in three types: unicornuate uterus with obstructed horn, double uterus with unilaterally obstructed horn, and double uterus with unilaterally obstructed vagina
- class IV: unusual configurations and combinations of defects
