Diagnostic Ultrasound - Abdomen and Pelvis

Appendicitis
(Left) Axial ultrasound
through an inflamed appendix
demonstrates a target-like st
appearance due to the
preservation of mural
stratification. Note the
surrounding echogenic
inflamed fat ſt and a
thickened inflamed parietal
layer of the peritoneum,
which is in contact with the
inflamed appendix. (Right)
Axial ultrasound of an
inflamed appendix
demonstrates increased mural
flow on power Doppler. Note
the surrounding echogenic
inflamed fat ſt and thickened
parietal peritoneum .
Diagnoses: Bowel
(Left) In this ultrasound of
obstructive appendicitis, note
the distended appendix with
an appendicolith st at the
base, curvilinear echogenicity
with posterior acoustic
shadowing , and lumen
distended with purulent
exudate and debris ſt. (Right)
Transvaginal ultrasound
depicts a distended inflamed
pelvic appendix with an
appendicolith ſt within the
lumen, representing acute
pelvic appendicitis. Note the
stratified mural appearance to
the appendicular wall.
(Left) Sagittal CECT
reconstruction shows a
thickened appendix ſt with
periappendicular fat stranding
representing retrocecal
acute appendicitis; ultrasound
has a limited role in identifying
these. (Right) Sagittal NECT
reconstruction in a different
patient shows a distended
appendix with an
appendicolith ſt at the base
and surrounding fat stranding
representing acute
appendicitis. Note the focus of
gas within the lumen st.
