Diagnostic Ultrasound - Abdomen and Pelvis

Intrauterine Device
Diagnoses: Female Pelvis
(Left) Longitudinal
endovaginal US of the cervix
shows a linear echogenic line
ſt in the cervical canal with
reverberation. This is the
normally positioned string of
the IUD, which may be seen
and should not be confused
with abnormal position of the
device. (Right) Coronal 3D US
shows a malpositioned copper
IUD in the lower uterine
segment and cervix with arms
extending into the
myometrium ſt.
(Left) Longitudinal
endovaginal US in a 28-yearold
patient with a missing IUD
string and pelvic pain shows
an empty endometrial cavity
with no IUD. (Right)
Longitudinal endovaginal US
of the left adnexa in the same
patient shows echogenic
linear structure representing
the IUD stem ſt adjacent to
the left ovary st.
(Left) Abdominal radiograph in
the same patient confirms a
perforated IUD in the left
adnexa. Note the position of
the IUD is too far lateral and
too high above the pelvic brim.
(Right) Intraoperative
photograph looking caudal
obtained during laparoscopy in
the same patient shows
forceps grasping the copper
IUD in the left adnexa. Note
healed perforation site on
posterior uterine body st and
inflamed broad ligament ſt.
