Diagnostic Ultrasound - Abdomen and Pelvis

Upper Tract Urothelial Carcinoma
(Left) Color Doppler
ultrasound of metastatic
urothelial cancer shows
vascular flow in the mass ,
confirming that this is a tumor.
Note the severe
hydronephrosis st and renal
vascular pedicle . (Right)
Coronal delayed phase CECT
shows metastatic urothelial
cancer of the left renal pelvis.
The pelvic mass extends into
the calyces . There is severe
hydronephrosis and cortical
thinning st as well as
hepatomegaly and liver
metastases ſt.
Diagnoses: Urinary Tract
(Left) Axial CECT in the portal
venous phase shows
circumferential wall
thickening of the right renal
pelvis , representing
urothelial carcinoma. Note the
left nephrectomy for
urothelial carcinoma. (Right)
Axial CT urogram in the same
patient differentiates the
contrast-filled lumen from the
tumor in the wall of the renal
pelvis . There was no
invasion of renal parenchyma.
(Left) Retrograde pyelogram
of UTUC shows a dilated upper
pole calyx with a filling defect
from the tumor oncocalyx .
There is a tumor extending
into the renal pelvis, with
stippling of contrast in the
interstices . (Right) Coronal
delayed phase T1 C+ MR
shows infiltrating urothelial
carcinoma. The renal shape
and contour are preserved.
The tumor is
hypoenhancing.
