Diagnostic Ultrasound - Abdomen and Pelvis

Peritoneal Space Abscess
(Left) Transverse ultrasound of
the pelvis in a diabetic woman
postdilatation and curettage is
shown. A thick-walled abscess
is present in the cul-de-sac ſt,
posterior to the bladder .
(Right) CECT of the same
patient confirms the thickwalled
abscess ſt. The
bladder is empty.
Diagnoses: Abdominal Wall/Peritoneal Cavity
(Left) Longitudinal ultrasound
of the midline pelvis in a
patient with a renal transplant
and a diverticular abscess ſt
is shown. The fat between the
abscess and the bladder is
inflamed. (Right) Coronal
NECT of the same patient
shows the abscess ſt between
the renal transplant and
the bladder . Inflammatory
fat stranding st is easier to
recognize on NECT.
(Left) Transverse ultrasound of
the left pelvis in a child post
recent surgery for complicated
appendicitis shows a
unilocular fluid collection ſt
with internal echoes. (Right)
CECT of the same patient
confirms the collection but is
superior at depicting the thick
enhancing wall ſt and
adjacent structures.
