Diagnostic Ultrasound - Abdomen and Pelvis

Abnormal Bladder Wall
Invasion by Pelvic Neoplasm
Tuberculous Cystitis
(Left) Longitudinal color
Doppler ultrasound shows
bladder wall thickening ſt
due to local invasion by
uterine cancer. Increased
vascularity is present in the
tumor tissue . (Right)
Transverse transabdominal
ultrasound shows a bladder
infected by TB with an
irregularly thickened bladder
wall ſt. Tuberculous cystitis
may be indistinguishable from
other forms of bacterial
cystitis.
Differential Diagnoses: Urinary Tract
Emphysematous Cystitis
Emphysematous Cystitis
(Left) Transverse
transabdominal ultrasound of
the bladder shows diffuse wall
thickening with several
echogenic foci in the bladder
wall (dependent and
nondependent) st with debris
ſt suggesting
emphysematous cystitis.
(Right) Axial contrast
enhanced CT through the
pelvis shows gas within the
bladder wall with ſt
perivesical/pelvic stranding st
(emphysematous cystitis).
Invasion by Pelvic Inflammatory Disease
Invasion by Pelvic Inflammatory Disease
(Left) Transverse oblique
transabdominal ultrasound
shows focal hypoechoic mass
in the right bladder wall ſt
confirmed as endometriotic
implant. (Right) Coronal
reformat CECT in this patient
with known Crohn disease,
shows asymmetric right
bladder wall thickening ſt
secondary to fistulous
communication st with small
bowel loops (enterovesical
fistula).
