Image Based Question-65216

The uterine anomaly as shown in the 3D endovaginal ultrasound below occurs due to?

A. Incomplete fusion of uterine cavity.

B. Incomplete fusion of paramesonephric duct.

C. Incomplete fusion of mesonephric duct.

D. Incomplete formation of vagina.

Correct Answer » B Explanation

Ans;B .Incomplete fusion of paramesonephric duct.

The uterine anomaly as shown in the 3D endovaginal ultrasound above represents bicornuate uterus.

Pathophysiology

• A bicornuate uterus is formed during embryogenesis.

• The fusion process of the upper part of the paramesonephric ducts is altered. As a result, the lower part of the uterus is unitary while the upper part is bifurcated.

• Bicornuate uterus is due to incomplete fusion of paramesonephric duct.

• Mullerian duct is synonymous to paramesonephric duct whereas wolffian duct is synonymous of Mesonephric duct.

Extra Edge:

• Fate of Para mesonephric Ducts (Mullerian ducts)
