Diagnostic Ultrasound - Abdomen and Pelvis

Functional Ovarian Cyst
(Left) Typical anechoic
appearance of the functional
cyst ſt is shown on routine
pelvic ultrasound, with
surrounding ovarian
parenchyma (calipers). (Right)
Functional ovarian cysts can
become large and the
surrounding parenchyma
compressed to a thin rim st.
When presenting with pelvic
pain, pulse Doppler should be
used to confirm arterial and
venous waveforms.
Diagnoses: Female Pelvis
(Left) CLC are often
complicated by hemorrhage
(calipers). Hemorrhagic CLC
can have lace-like echoes and
thin septations ſt, and
typically spontaneously
resolve, as demonstrated on
this endovaginal grayscale
ultrasound of the ovary.
(Right) In this CLC, careful
evaluation of the posterior
cyst wall reveals a fluid/debris
level . The appearance is
consistent with a resolving
hemorrhagic cyst.
(Left) CLC can also appear
solid due to hemorrhage and
collapse of the cyst after
ovulation ſt. (Right) Color
Doppler ultrasound shows the
solid-appearing CLC has
increased vascularity, similar
in appearance to the "ring of
fire."
