Diagnostic Ultrasound - Abdomen and Pelvis

Abnormal Bladder Wall
Differential Diagnoses: Urinary Tract
(Left) Transverse
transabdominal ultrasound
shows diffuse bladder wall
thickening ſt with internal
debris and echoes st in a
patient with a urinary tract
infection, with positive
bacterial growth on urine
culture. (Right) Transverse
transabdominal ultrasound of
the urinary bladder shows
multiple large stones ſt with
diffuse wall thickening ,
suggesting chronic cystitis.
Bacterial Cystitis
Chronic Cystitis
(Left) Transverse
transabdominal ultrasound
shows a small capacity
bladder with wall thickening
and an irregular inner bladder
surface (trabeculations) ſt in
a neurogenic bladder. (Right)
Longitudinal transabdominal
ultrasound shows diffuse
bladder wall thickening
secondary to benign prostatic
hyperplasia with a
lobulated contour, indenting
the bladder base. A common
cause of chronic bladder
outlet obstruction in elderly
male patients.
Neurogenic Bladder
Chronic Bladder Outlet Obstruction
(Left) Longitudinal color
Doppler US of the bladder
shows multiple solid masses
ſt arising from the posterior
wall of the bladder with
internal vascularity consistent
with transitional cell
carcinoma of the bladder.
Note the echogenic debris st
within the bladder caused by
associated hematuria. (Right)
Transverse color Doppler
image of the bladder shows an
irregular echogenic mass ſt
arising from the posterior wall
of the bladder with internal
vascularity consistent with
bladder carcinoma.
