Diagnostic Ultrasound - Abdomen and Pelvis

Cystic Renal Mass
Differential Diagnoses: Kidney
(Left) Longitudinal color
Doppler ultrasound of the
kidney demonstrates an
exophytic cortical lesion ſt,
apparently solid but with no
internal color flow. Further
evaluation with MR showed
that this was a hemorrhagic
cyst. (Right) Longitudinal
ultrasound of the right kidney
shows a cyst ſt with
dependent highly echogenic
milk of calcium st. The layer
moved on repositioning the
patient.
Complex Cysts: Hemorrhagic, Infected, or
Proteinaceous
Complex Cysts: Hemorrhagic, Infected, or
Proteinaceous
(Left) Transverse ultrasound
shows a multiseptated, fluidfilled
lesion ſt in the renal
sinus. It may be difficult to
distinguish from
hydronephrosis if the calyces
appear dilated; however,
enhanced CT or MR can be
definitive. (Right) Longitudinal
ultrasound of the kidney
shows an exophytic lower pole
cyst ſt, which did not
communicate with the
moderate hydronephrosis st.
Renal Sinus Cysts
Hydronephrosis
(Left) Longitudinal ultrasound
of the right kidney shows a
small right kidney with
multiple cysts of various sizes
ſt in a patient on dialysis.
Ascites is present . (Right)
Longitudinal ultrasound of the
right abdomen shows a large
kidney with multiple cysts ſt
abutting the upper pole of a
renal transplant . Cysts st
were also present in the
enlarged liver.
