Therefore, imaging studies of the urinary tract are fundamental in paramesonephric duct anomalies, particularly in the HWW syndrome.
It is postulated that these tumours arise from mullerian or paramesonephric duct remnants, which were deposited when the ovary descended during embryogenesis.
Sinowatz (2010) describes that the vagina has two origins: one anterior, derived from the paramesonephric ducts and one posterior derived from the urogenital sinus.
During the formation of the reproductive system, paramesonephric ducts (also called Mullerian ducts) differentiate into the oviduct, uterus, cervix, and upper one-third of the vagina.
An imperforate hymen results from failure of the caudal paramesonephric ducts to fuse with the urogenital sinus, leading to an obstruction located between the vagina and the vestibule, just cranial to the opening of the urethra [1, 2].
Congenital cysts may be derived from urogenital sinus or from mesonephric (Gartner cyst) or paramesonephric (Mullerian cyst) remnants.
Prostatic utricle cysts result from the regression of the Mullerian paramesonephric ducts or decreased androgenic stimulation of the urogenital sinus.
The uterus develops from celomic epithelium during the 6th week of development during which it invaginates to form paramesonephric duct (mullerian duct).
Hymen arises from the paramesonephric ducts and developmental aberrations of which may lead to a condition known as persistent hymen.
17) Testicular appendages are remnants of the paramesonephric duct and are usually located at the superior testicular or epididymal head.
7 Paramesonephric ( Mllerian) ducts develop into uterine tubes, uterus and superior part of vagina.
The paramesonephric duct or Mullerian duct first appears in the human embryo at the 10mm stage and begins to regress in the male due to Mullerian inhibiting substance (MIS) (1).
