Diagnostic Ultrasound - Abdomen and Pelvis

Uterine Anomalies
Diagnoses: Female Pelvis
(Left) Slightly oblique
transverse transvaginal
ultrasound showing
separation of the
endometrium as well as
indentation of the external
uterine contour , consistent
with bicornuate uterus. An
early gestational sac is present
in the left horn ſt. (Right)
Transvaginal ultrasound
obtained coronal to a slightly
deviated uterus shows a
gestational sac within 1
uterine horn ſt and fluid and
debris within the other .
The fundal indentation of this
bicornuate uterus is visible
superiorly .
(Left) Coronal transvaginal
ultrasound in a complex case
shows a normal endometrium
ſt on the left side with thick
muscle connecting to
another horn, which lacked
the normal endometrial line
. The precise anatomy was
not able to be defined
sonographically. The left ovary
was normal st. (Right) Right
sagittal ultrasound of the
right adnexa in the same
patient shows a complex cystic
right ovarian mass ſt,
consistent with an
endometrioma.
(Left) T2 MR in the same
patient better depicts the
anatomy, showing a normal
left horn ſt and an obstructed
right horn with distended
endometrium and
associated right
endometrioma with T2
shading . This was a
unicornuate uterus with a
noncommunicating cavitary
right horn. (Right)
Hysterosalpingogram shows
only the endometrial cavities
ſt; however, the degree of
separation > 110° is consistent
with a bicornuate uterus.
There is normal free spillage
of contrast bilaterally st.
