Diagnostic Ultrasound - Abdomen and Pelvis

Unusual Ectopic Pregnancies
(Left) Longitudinal
transvaginal ultrasound shows
a gestational sac with a fetal
pole implanted in the
anterior wall of the cervix.
Note the large tortuous
vessels around the
implantation site st and the
endocervical canal posterior to
the EP ſt. (Right)
Corresponding longitudinal M-
mode ultrasound shows
cardiac activity in the live
cervical ectopic pregnancy
Diagnoses: Female Pelvis
(Left) Color Doppler
ultrasound in the same patient
shows marked vascularity
around the implantation site
ſt. (Right) Sagittal T2 HASTE
MR shows an hourglass
configuration of the uterus
with a gestational sac
containing a fetal pole
centered in the cervix. T2-
hyperintense trophoblastic
tissue is seen extending into
the cervical wall ſt.
(Left) Longitudinal
transabdominal ultrasound
shows an empty uterus ſt and
a large extrauterine
gestational sac which
contained a live fetus. Surgical
exploration confirmed a
secondary abdominal ectopic
pregnancy which had ruptured
from the tube and parasitized
blood flow from the
peritoneum. (Right)
Longitudinal transabdominal
ultrasound in the same patient
shows echogenic free fluid
around the liver ſt indicating
significant hemoperitoneum.
