Diagnostic Ultrasound - Abdomen and Pelvis

Appendicitis
(Left) Axial ultrasound shows
an appendicular tip ſt with
loss of the stratified mural
appearance representing
gangrenous "tip appendicitis."
Note the surrounding
echogenic inflamed fat st.
(Right) Oblique axial
ultrasound in the same patient
shows a more proximal part of
the appendix with an inflamed
thickened wall ſt and
surrounding inflamed
echogenic fat st. (Courtesy V.

Diagnoses: Bowel
(Left) Sagittal oblique
ultrasound through the right
flank shows an abscess
with debris and an
appendicolith ſt at the
dependent part from
perforated appendicitis. Note
the abscess extending
cranially anterior to the right
kidney . (Courtesy A. Law,
MD.) (Right) Sagittal oblique
ultrasound in the same patient
(at a lower level) shows the
proximal part of the inflamed
appendix ſt, the adjacent
collection from tip
perforation, and the
surrounding inflamed fat .

(Left) Sagittal CECT shows an
inflamed, distended appendix
st with surrounding
periappendicular
inflammatory changes. Note
soft tissue ſt at the base of
the appendix that is causing
the obstruction. (Right) Axial
CECT through the
appendicular base from the
same patient shows the soft
tissue ſt at the appendicular
base in continuity with
eccentric soft tissue thickening
involving the posterior wall
of the cecum. At surgery, there
was an infiltrative cecal
carcinoma, causing
obstruction and infection.
