Flashcards in Uterine Pathology Deck (76)
This is the most common type of female reproductive tract anomaly.
mullerian duct defects
These are the embryonic tubes that develop to form the upper vagina, cervix, uterus, and fallopian tubes.
T/F? Mullerian ducts are present in the embryo of both genders.
What duct develops into the male reproductive organs?
The development of the mullerian ducts is controlled by the presence of absence of...
anti-mullerian hormone (AMH/MIF/MIH)
What should the sonographer evaluate in all cases of uterine anomalies?
the urinary tract
Urinary tract abnormalities are found in approx __% of patients with uterine anomalies.
The ___ do NOT develop from the mullerian duct and are generally normal in the presence of mullerian anomalies.
What are the four categories of anomalous internal genitalia development?
4. structures to disappear
This formation anomaly results in complete absence of the vagina, cervix, uterus and fallopian tubes.
This formation anomaly can result in the absence of the upper vagina and cervix with persistence of the uterus and fallopian tubes or the more common unicornuate uterus and single fallopian tube.
What's the most common partial agenesis mullerian anomaly?
This mullerian anomaly may be suspected when the uterus appears small and laterally positioned.
The poorest fetal survival among all MAs has been reported with a ___ anomaly.
A missing __ or other __ problems may accompany a unicornate uterus.
Where might the ovary on the rudimentary side of a UU be found?
further up by the ribs
A rudimentary horn that does not communicate with the normal side leads to...
retrograde menstruation, endometriosis, and probably a resection.
With this fusion anomaly there may be complete duplication of the vagina, cervix and uterus.
This MA has the best pregnancy outcomes.
T/F? In a UD each separate uterus is narrower than a normal uterus.
In 67% of cases, a didelphus uterus is associated with...
two vaginas separated by a thin wall.
In this fusion anomaly there's a single vagina and cervix but variable lack of fusion of the upper uterine cavity.
A serosal indentation of more than __ is indicative of a bicornuate uterus.
This MA has relatively few pregnancy complications, but breech presentation is the most common.
These two MAs need to be distinguished from each other, so a single cervix should be confirmed.
uterus didelphys and bicornuate uterus
This may be confused with a uterine or adnexal mass if the central endometrial echo complex is not seen in one of the horns.
The subset of MA features a single vagina and cervix and two uterine horns which are partially fused.
This subset of MA features a double or single vagina, a double cervix, and two uterine horns which are partially fused.
This is the mildest fusion anomaly, resulting in a slight indentation of the uterine fundus and mostly normal endometrial cavity.
