Chapter 3 Congenital Abnormalities Flashcards
Anterior flexion of the uterine fundus relative to the cervix in the saggital plane.
Anteflexion
What will formed from the middle or pelvic portion of the urogenital sinus?
Female urethra
Triad of cloacal exstrophy:
Omphalocele
Bladder exstrophy
Imperforate anus
Remnants of the mesonephric or wolffian vestiges.
Gartner duct
What will be form d from the caudal portion of the urogenital sinus?
Vagina and glands
Intraabdominal wolffian remnants in the female in the mesovarium.
Epoophoron
This malformation is a mild deviation from the normally developed uterus.
Class VI, Arcuate uterus
Uterus is formed by union of the two mullerian ducts at approximately what week?
10th week
Vaginal canalization is generally completed at what week?
20th week
Characterized by an exposed bladder lying outside the abdomen.
Bladder exstrophy
Associated finding commonly included in ballder exstrophy.
Widened symphisis pubis.
Mullerian anomaly arises from complete lack of fusion that results in two entirely separate hemiuteri, cervix and two vaginas.
Class III, Uterine Didelphys
A small, benign cyst attached by a pedicle to the distal end of the fallopian tube.
Hydatid of Morgagni
Common anomaly that forms as lack of fundal fusion results in two hemiuteri, with only one cervix and vagina.
Class IV, Bicornuate Uterus
Noted at birth, suggestive of fetal exposure to excessive androgrens.
Clitoromegaly
Apparent during adolescence, with findings of amenorrhea, cyclic abdominal pain and a bulging bluish introital membrane.
Imperforate hymen
A small benign cyst attached to a pedicle to the distal end of the fallopian tube.
Hydatid of Morgagni
Persistent entrapment of the pregnant uterus in the pelvis may lead to extensive lower uterine dilatation.
Sacculation
Can be caused by mullerian hypoplasia or agenesis.
Class I , Mullerian Agenesis
What organ arises from the genital ridge?
Ovaries
Syndrome in which upper vaginal agenesis is typically associated with hypoplasia or agenesis.
Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome
Obstructed hemivagina and ipsilateral renal agenesis (OHIVA), is also known as
Herlyn-Werner-Wunderluch syndrome
Uterine rotation exceeds 180 degrees.
Uterine torsion
Elongated vagina above the level of the fetal head that is deeply placed into the pelvis.
Sacculation or abdominal pregnancy
An anomaly with an underdeveloped or rudimentary horn may be absent.
Class II, Unicornuate Uterus
This is posterior uterine fundal flexion in the sagittal plane.
Retroflexion
This anomaly is caused when a resorption defect leads to persisitent complete or partial longitudinal uterine cavity septum.
Class V, Septate Uterus
Maternal estrogen secretions collect to form a bulging translucent yellow-gray mass.
Hydro or Mucocolpos
A Mullerian abnormality that increases risk to small cell cervical ca, vaginal clear cell adenoca, cervical intraepithelial neoplasia and vaginal adenosis.
Class VII, Diethylstilbesterol Reproductive Tract Abnormalities
Urinary tract develops from?
Wolffian ducts or mesonephros
What is an intra abdominal wolffian remnants along the uterus in the female tract?
Paraoophoron
